EVALUATION OF CONCRETE
A. Structural analysis and/or additional design calculations and testing may be required
when strength of structure is considered potentially deficient.
1. Core tests may be required when strength of concrete in place is considered
potentially deficient.
2. If core tests are inconclusive or impractical to obtain or if structural analysis and
design calculations does not confirm the safety of the structure, load tests may be
required and their results evaluated in accordance with AASHTO 2020.
B. Reinforce or replace concrete work judged inadequate by structural analysis or by
results of a load test with additional construction, if so directed by the Client at the
Contractor's expense.

B. Concrete proportions:
Proportion mixture to provide desired characteristics using one of following methods for
each specified strength and each type of concrete:
1. Method 1:
Use when combination of materials is to be evaluated and proportions selected is on
basis of trial mixes. Make mixtures having suitable proportions and consistencies
based on ACI 211 .1, using at least three different water-cement ratios which will
produce a range of strengths encompassing those required. Design trial mixes to
produce a slump within 25 mm of maximum permitted. Report temperature of
concrete used in trial batches. For each water-cement ratio, make at least three
compressions test cylinders for each test age, and cure in accordance with ASTM
C192. Test for strength at 28 days or at earlier or later age in accordance with ASTM
C39. From results of these tests plot a curve showing relationship between watercement ratio and compressive strength. From this curve, select water-cement ratio to
be used to produce average strength required as described in paragraph B.2. Use
cement content and mixture proportions such that water-cement ratio is not exceeded
when slump is maximum permitted. Base field control on maintenance of proper
cement content, slump, and air content.
2. Method 2:
In lieu of trial batches to establish required average strength level, as described
above for Method 1, appropriate field test data for concrete made with similar
ingredients may be used. Proposed mixture proportions subject to approval by the
Client. Determine ability to produce required average strength calculated, in
accordance with following paragraph, on basis of strength test record of 30 or more
tests made during past year which will permit establishing, directly or by interpolation,
water-cement ratio corresponding to required average strength.
a. Required average strength. Where-production facility has a control record, based
on at least 30 consecutive strength tests of a similar mix or mixes obtained within
past year representing similar materials and conditions to those expected,
average strength used as basis for selecting proportions shall exceed specified
strength (f'c) by at least:
(1)
3.15 MPa if standard deviation is less than 2.1 MP a.
(2)
3.85 MPa if standard deviation is 2.1 0 to 2.80 MP a.
TECHNICAL SPECIFICATIONS
867
(3)
4.90 MPa if standard deviation is 2.80 to 3.50 MPa.
(4)
6.30 MPa if standard deviation is 3.50 to 4.20 MPa.
b. If standard deviation exceeds 4.20 MPa or if a suitable record of strength test
performance is not available, select proportions to produce an average strength
at least 8.40 MPa greater than specified strength (f'c).
c.
Strength test history used to determine standard deviation will be considered to
comply with above requirement for 30 consecutive strength tests if tests
represent either a group of 30 consecutive batches of same class of concrete or
statistical average for two groups total 30 or more batches. Tests used in
establishing standard deviation shall represent concrete produced for a specified
strength or strengths within 7.0 MP a of that required for proposed work; changes
in materials and proportions within number of background tests shall not have
been more closely restricted than for proposed work.
3. Method 3:
When test data for materials to be used in concrete are not available or will not be
determined, proportion so that water-cement ratio does not exceed 0.40.
a. Method 3 is not applicable to:
(1)
Concrete containing admixtures other than those used exclusively for
entraining air.
(2)
Prestressed concrete.
(3)
Concrete designed for specified strengths f'c in excess of 20.0 MPa.
C. Concrete for floors:
Provide a trial slab to permit evaluating finishing properties, hardness, and appearance
of concrete proposed for use. Make with proposed materials and proportions, using
equipment and personnel comparable with those to be employed on work. Use concrete
capable of being finished with slump not exceeding that specified.

3.2
CONTRACTION (CONTROL) JOINTS
A. Slabs
1. Differential movement in slabs must be accommodated by contraction joints spaced
at (4500 - 6000 mm) intervals.
2. If columns are located farther apart than 6000 mm intermediate joints should be
provided in the floor. The resulting panels should be approximately square;
elongated and L-shaped panels should be avoided.
3. In driveways and sidewalks contraction joints should be spaced at intervals about
equal to the slab width but drives and walks wider than about 3000 - 4000 mm
should have a longitudinal joint down the centre. Spacing of contraction joints in
patios should not exceed 3000 in either direction.
4. All contraction joints should be continuous, not staggered or offset.
5. One method of making contraction joints is by sawing a continuous slot to a depth
of one-fourth the thickness of the slab [but not less than 25 mm].
6. On thicker slabs use a power saw with a masonry cutting blade, cutting at least 1/4
the thickness of the slab. Cutting should be done as soon as possible after the
concrete hardens. The concrete is hard enough when the blade does not dislodge
aggregate and when the edges of the cut do not ravel. If random cracking occurs
before sawing, then the sawing has been delayed too long. Power saws may also
be used in thin slabs. Unsuitable choice of saw blades can result in slow cutting and
excessive blade wear. The manufacturer should be consulted about choice of
blades for the aggregate being used.
7. Preformed plastic or metal strips for making contraction joints are available for
insertion into freshly placed concrete. Prior to insertion, a string line should be
snapped along each joint line to help make the joints straight. A slot should be cut
in the fresh concrete with a trowel or other sharp tool before each strip is inserted. If
the joint device requires removal of the top of the device, the top should be
removed just prior to the flat trawling.
8. Where wheeled traffic is involved and durable joints are required, uneven joints or
joints with a wide radius should be avoided. Hand tooled joints, wood strip joints, or
'T' strips should not be used, nor should any other jointing method be used which
results in uneven joints or wide radius joints.
TECHNICAL SPECIFICATIONS
879
9. Contraction joints for interior floors may be filled with certain epoxy resins or sealed
with elastomeric sealants as described in the report of ACI 504 application of epoxy
materials should be delayed as long as possible so that the majority of the
shrinkage has occurred, this should be not less than 3 months. Elastomeric
sealants are used only where they will not be subject to small hard - wheel traffic.
B. Walls
1. Same procedure & techniques as for slabs.
2. First joints should occur 3000 to 4000 mm from a corner.
3. Joints in reinforced concrete walls shall located such as maximum spacing does not
exceed 1 0000 mm.
3.3
ISOLATION JOINTS
A. The floor must be separated structurally from other building elements to accommodate
differential horizontal and vertical movement. Isolation joints must be used at junctions
with walls, columns, machine foundations, and footings, or other points of restraint,
such as drainpipes, fireplaces, pumps, stairways, and so forth. These may be produced
by inserting expansion joint fillers before or during the concreting operations.
B. The joint filler should extend full depth of the joint and not protrude above it.
C. If vehicles are to pass over isolation joints that have no provision for load transfer, such
as at doorways, the slab should be thickened by approximately 25 percent and tapered
to the required thickness at a slope of not more than 1 in 5.
D. Isolation joints may be formed with preformed asphalt impregnated fibre sheeting or
similar materials placed before concreting begin, and detailed.

specified in ASTM C 94 and AASHTO 157 may be required, as specified below.
Proposed changes in mixing procedures other than the specified, must be accepted
by the Engineer before implementation.
3.2
FIELD QUALITY CONTROL
A. Employ an approved separate testing laboratory to perform field quality control testing.
B. Quality Control Testing During Construction:
TECHNICAL SPECIFICATIONS
915
1. Sampling Fresh Concrete: Conform to ASTM C 172, except modified for slump to
comply with ASTM C 94.
2. Slump: Conform to ASTM C 143; one test for each concrete load at point of
placement and one for each set of compressive strength test specimens.
3. Concrete Temperature: Test daily when air temperature is 26ºC. And above, and
each time a set of compression test specimens made. Test concrete temperature
throughout the pour when the ambient temperature exceeds 30ºC.
4. Compressive Strength Tests: Provide one set of 6 standard cylinders for each 50
m3 or fraction thereof, of each mix design placed in any one day or for each 300 m2
of surface area placed; 2 specimens tested after 7 days, 3 specimens tested after
28 days, and one specimen retained in reserve for later testing if required.
Additional test specimens may be cast for construction progress control and form
stripping.
a. When the frequency of testing will provide less than 5 strength tests for a
given mix design, conduct testing from at least 5 randomly selected batches
or from each batch if fewer than 5 are used.
b. When the strength of field-cured cylinders is less than 85 percent of
companion laboratory-cured cylinders, evaluate current operations and
provide corrective procedures for protecting and curing the in place
concrete.
5. Testing laboratory shall report test results in writing to ·the Engineer, and ReadyMix supplier on the same day that tests are made. Reports of compressive strength
tests shall contain Project identification name and number, date of concrete

and 28-day tests.
C. Additional Tests:
1. The testing service will make additional tests of in-place concrete when test results
indicate the specified concrete strengths and characteristics have not been attained
in the structure, as directed by the Engineer. The testing service shall conduct tests
to determine the strength and characteristics of the in-place concrete by
compression tests on cured cylinders complying with ASTM C42, or by load testing
TECHNICAL SPECIFICATIONS
916
specified in ACI 318, or other acceptable non-destructive testing methods, as
directed.
D. Evaluation of Quality Control Tests:
1. Do not use concrete delivered to the final point of placement which has slump
outside the specified values.
2. Compressive strength tests for laboratory-cured cylinders will be considered
satisfactory if the averages of a set of three consecutive compressive strength tests
results equal or exceed the 28-day design compressive strength of the type or class
of concrete.
No individual strength test shall fall below the required compressive strength by
more than the value of 2. 75 N/mm2.
a. Strength tests of specimen cured under field conditions may be required by
the Engineer to check the adequacy of curing and protecting of the
concrete placed. Specimens shall be molded by field quality control
laboratory at the same time and from the same samples as the laboratory
cured specimens.
b. Provide improved means and procedures for protecting concrete when the
28-day compressive strength of field-cured cylinders is less than 5% of
companion laboratory-cured cylinders.
c.
When laboratory-cured cylinder strengths are higher than the minimum
required compressive strength, field-cured cylinder strengths need not
exceed the minimum required compressive strength by more than 2.75
MPa even though criterion is not met.
d. If individual test of laboratory-cured specimens produce strengths more
than 2.75 MPa below the required minimum compressive strength, or if
tests of field-cured cylinders indicate the deficiencies in protection and
curing, provide additional measures to assure that the load-bearing
capacity of the structure is not jeopardized. If the likelihood of low-strength
concrete is confirmed and computations indicate the load-bearing capacity
may have been significantly reduced, tests of cores drilled from the area in
question may be required.
TECHNICAL SPECIFICATIONS
917
e. If the compressive strength tests fail to meet the minimum requirements
specified, the concrete represented by such tests will be considered
deficient in strength and subject to correction at no extra cost to the Owner.
3.3

forms and reinforcing steel.
E. Polyethylene vapor barrier shall be placed between concrete blinding and concrete
footing leaving extra width on both sides which shall then be tucked up to wrap the
concrete footing after the form removal.
3.4
CONCRET PLACEMENT
A. General: Place concrete in compliance with the practices and recommendations of ACI
301 and ACI 304 and as specified herein:
1. Deliver concrete from central plant to the place of final deposit in a continuous
manner and without segregation or loss of ingredients. Suspend placing when the
sun, heat, wind, or limitation of facilities prevents proper finishing and curing of the
concrete. Place concrete in the forms or excavation as close as possible in final
position, in uniform, approximately horizontal layers, not over 600 mm deep unless
otherwise directed.
Do not drop concrete freely for more than 1.5 m, nor allow it to drop freely through
congested rebaring areas which could cause segregation. This drop distance may
be increased by the Engineer at his discretion where it can be shown by Contractor
that a greater drop will not result in segregation. Conduits and pipes shall not be
embedded in concrete unless specifically indicated or specified. Do not place
TECHNICAL SPECIFICATIONS
918
concrete in any form until forms have been inspected by the Engineer and
permission has been given to proceed.
2. Do not use concrete which becomes non-plastic and unworkable or does not meet
the required quality control limits or which has been contaminated by foreign
materials. Do not use retempered concrete. Remove rejected ·concrete from the
project site and dispose of it off site at no extra cost to Owner.
B. Transportation Time Interval:
1. Concrete mixed in central plant and transported by non-agitating equipment shall
be placed in the forms within 30 minutes. Concrete transported in truck mixers or
truck agitators shall be delivered to the site and placed in the forms within 60
minutes. This time limitation may be increased by the Engineer at his discretion
when additional superplasticizer is added to the concrete mix so as to retard the
initial set for greater periods. In no case will additional water be added to the mix
(tempering) after the concrete leaves the batching plant.
C. Conveying Concrete:
1. Concrete may be conveyed by chute, conveyor, or pump if so approved by the
Engineer. Aluminum chutes or pipelines shall not be used for conveying concrete.
Approvals will not be given for chutes or conveyors requiring changes in the
concrete design mix for desired operation. Conveying equipment shall be cleaned
when not in use.
2. Chutes and Conveyors: Chutes shall be rounded in cross section, rigid in
construction, protected from overflow and slopes not exceeding one vertical to three
horizontal. Conveyors shall be designed to operate assuring uniform flow of
concrete without segregation of ingredients, loss of mortar, or change in slump.
3. Pumps: Placing concrete by pumping methods shall conform with ACI 301 Chapter
8. Operate and maintain pumps so that a continuous stream of concrete is
delivered into the forms without air pockets, segregation, or change in slump
exceeding 5 cm. Use pumps which can pump mixes as designed. Mixes shall not
be adjusted to accommodate smaller pumps.
D. Placing Concrete into Forms:
1. Deposit concrete in the forms for horizontal slabs in horizontal layers not deeper
than 60 mm unless additional thickness is permitted by the Engineer and in a
manner to avoid inclined construction joints. Where placement consists of several
layers, place each layer while preceding layer is still plastic to avoid cold joints.
TECHNICAL SPECIFICATIONS
919
2. Consolidate concrete placed in forms with mechanical vibrating equipment
supplemented by hand-spading, rodding or tamping. Use equipment and
procedures for consolidation of concrete in accordance with the recommended
practices of ACI 309, to suit the type of concrete and project conditions. Vibration of
forms and reinforcements will not be permitted.
3. Do not use vibrators to transport concrete inside of forms. Insert and withdraw
vibrators vertically at uniformly spaced locations not farther than the visible
effectiveness of the machine. Place vibrators to rapidly penetrate the layer of
concrete and at least 150 mm into the preceding layer. Do not insert vibrators into
lower layers of concrete that have begun to set. At each insertion, limit the duration
of vibration to the time necessary to consolidate the concrete and complete
embedment of reinforcement and other embedded items without causing
segregation of the mix.
4. In order to allow for shrinkage or settlement, at least 2 hours shall elapse after
placing concrete in walls, columns or stems of deep T-beams before depositing
concrete in girders, beams and slabs supported thereof, unless otherwise specified
or shown on the plans.
5. Place concrete in girders, slabs and shallow T-beam construction in one continuous
operation for each span, unless otherwise detailed. Deposit concrete uniformly for
the full length of the span then bring up evenly in horizontal layers.
6. Place concrete in columns in one continuous operation to the bottom of the deepest

METHODOLOGY
A. Repair surface defects immediately after form removal.
B. Repair defective areas: Remove all honeycombed and other defective concrete down to
sound concrete. Chip if necessary to make edges perpendicular to surface or slightly
undercut. No featheredges will be permitted. Dampen area to be patched and an area
at least 150 mm wide surrounding it to prevent absorption of water from patching
mortar. Prepare a bonding grout of approximately 1 part cement to 1 part fine sand
passing a No.30 mesh sieve. Mix to consistency of thick cream, and then brush into
surface.
C. Make patching mixture of same materials and of approximately same proportions as
used for concrete, except omit coarse aggregate. Mortar shall consist of not more than
1 part cement to 2-1/2 parts sand by damp loose volume. Mix white and gray portland
cement to produce a colour matching colour of surrounding concrete, as determined by
a trial patch. Add no more mixing water than necessary for handling and placing. Mix
patching mortar in advance and allow to stand with frequent manipulation, without
addition of water, until it has reached stiffest consistency that will permit placing.
D. After surface water has evaporated from area to be patched, brush bond coat into
surface. When bond coat begins to lose water sheen, apply patching mortar.
Thoroughly consolidate mortar into place and strike off so as to leave patch slightly
higher than surrounding surface. To permit initial shrinkage, leave undisturbed for at
least 1 hour before final finish. Keep patched area damp for 7 days. Do not use metal
tools in finishing a patch which will be exposed.
TECHNICAL SPECIFICATIONS
935
E. Fill and finish tie holes: Clean and thoroughly dampen tie holes; fill solid with patching
mortar. Round tie holes less than 6 mm diameter x 37 mm deep in rough form finished
surfaces need not be filled.
F. Proprietary materials: If permitted or required, proprietary compounds for adhesion or
as patching ingredients may be used in lieu of or in addition to foregoing patching
procedures.
Use
such
compounds
in
accordance
with
manufacturer's
recommendations.
3.4
ROUGH FORM FINISH
Rough form finish: No selected form facing materials are specified for rough form finish
surfaces. Patch defects. Chip or rub off fins exceeding 6 mm in height. Otherwise, leave
surfaces with texture imparted by forms.
3.5
SMOOTH FROM FINISH
A. Smooth form finish: Use form facing material to produce a smooth, hard, uniform texture
on concrete. It may be plastic coated plywood, metal, plastic liners, or other approved
material capable of producing desired finish. Arrange facing material orderly and
symmetrically, with number of seams kept to practical minimum. Support by studs or
other backing capable of preventing excessive deflection. Do not use material with
raised grain, patches, or other defects which will impair texture of concrete surface.
B. Patch tie holes and defects. Remove all fins completely.
C. When surface texture is impaired and form joints misaligned by more than 3 mm grind,
bushammer, or correct affected concrete as directed by Client and/or Engineer Slurry
grout areas evidencing minor mortar leakage to match adjacent concrete. Repair major
mortar leakage as a defective area. When in opinion of Client and/or Engineer,
workmanship is less than an acceptable standard for a smooth form finish, provide one
of rubbed finishes indicated at no additional cost to Client and/or Engineer.

Produce rubbed finishes on concrete with a smooth form finish. Where smooth rubbed
finish is to be applied, remove forms and perform necessary patching as soon af1er
placement as possible without jeopardizing structure.
TECHNICAL SPECIFICATIONS
936
B. Rubbed finish – smooth
Smooth rubbed finish: Produce smooth rubbed finish on newly hardened concrete no
later than day following form removal. Wet surfaces and rub with carborundum brick or
other abrasive until uniform colour and texture are produced. Use no cement grout other
than cement paste drawn from concrete itself by rubbing process.
C. Rubbed finish - grout cleaned
Grout cleaned finish: Undertake no cleaning operations until all contiguous surfaces are
completed and accessible. Mix 1 .part portland cement and 1-1/2 parts fine sand with
sufficient water to produce a group having consistency of thick paint. Mix white and gray
portland cement to match colour of surrounding concrete, as determined by a trial
patch. Wet surface of concrete sufficiently to prevent absorption of water from grout and
apply grout uniformly. Immediately after applying grout, scrub surface vigorously with a
cork float or stone to coat surface and fill all air bubbles and holes. While grout is still
plastic, remove excess grout by working surface with a rubber float, sack, or other
means. After surface whitens from drying, rub vigorously with clean burlap. Keep finish
damp for at least 36 hours after final rubbing.
D. Rubbed finish - cork floated
Cork floated finish: Remove forms at an early stage, within 2 to 3 days of placement
where possible. Remove ties. Remove all burrs and fins. Mix one part portland cement
and one part fine sand with sufficient water to produce a stiff mortar. Dampen wall
surface. Apply mortar with firm rubber float or with trowel, filling all surface voids.

FINISHED OF RELATED UNFORMED SURFACES (EXCEPT SLABS)
A. Strike smooth tops of walls or buttresses, horizontal offsets, and similar unformed
surfaces occurring adjacent to formed surfaces after concrete is placed.
B. Float to a texture reasonably consistent with that of formed surfaces.
C. Continue final treatment on formed surfaces uniformly across unformed surfaces.
3.8
SLAB FINISHING – GENERAL
A. Place slabs to tolerances specified.
B. Unspecified slab finish: When type of finish is not indicated, use following finishes as
applicable:
TECHNICAL SPECIFICATIONS
937
1. Surfaces intended to receive bonded applied cementitious applications: Scratched
finish.
2. Surfaces intended to receive roofing (except future floors), waterproofing
membranes, or sand bed terrazzo: Floated finish.
3. Floors and roof surfaces which are future floors intended as walking surfaces or for
reception of thin sheet covering or epoxy coverings: Trowelled finish.
4. Sidewalks, garage floors and ramps: Broom or belt finish.
5. Exterior platforms, steps, and landings, exterior and interior pedestrian ramps, not
covered by other finish materials: Nonslip finish.
C. Scratched slab finish
After concrete has been placed, consolidated, struck off, and leveled to a Class C
tolerance, roughen surface with stiff brushes or rakes before final set.
D. Floated slab finish
After concrete has been placed, consolidated, struck off, and leveled, do not work
further until ready for floating. Begin floating when water sheen has disappeared and
surface has stiffened sufficiently to permit operation. During or after first floating check
planeness of entire surface with a 3 M straightedge applied at not less than two different
angles. Cut down all high spots and fill all low spots during this procedure to produce a
surface within Class B tolerance throughout. Refloat slab immediately to a uniform
sandy texture.
E. Trowelled slab finish
First float-finish surface. Next power trowel, and finally hand trowel. First trowelling after
power floating shall produce a smooth surface which is relatively free of defects but
which may still show some trowel marks. Perform additional trowelling by hand after
surface has hardened sufficiently. Final trowel when a ringing sound is produced as
trowel is moved over surface. Thoroughly consolidate surface by hand trowelling. Leave
finished surface essentially free of trowel marks, uniform in texture and appearance and
plane to a Class B tolerance. On surfaces intended to receive floor coverings, grind off
any defects which would show through ·floor covering.
F. Broom or belt finish
Immediately after concrete has received float finish, give it a coarse transverse scored
texture by drawing a broom or burlap belt across surface.
TECHNICAL SPECIFICATIONS
938
G. Non-slip slab finish
1. Aggregate: Crushed ceramically bonded aluminum oxide particles.
2. Blend
aggregate
with
portland
cement
in
proportions
recommended
by
manufacturer of aggregate.
3. Give surface a float finish.
4. Apply approximately two-thirds of blended material for required coverage to surface
by a method that insures even coverage without segregation. Begin floating
immediately.
5. After material has been embedded by floating, apply remainder of blended material
to surface at right angles to previous application. Make second application heavier
in any areas not sufficiently covered by first application. Follow with second floating
immediately.
6. After selected material has been embedded by two floating, complete operation
with a broomed finish.
H. Exposed aggregate slab finish
1. Immediately after surface of concrete has been leveled to a Class B tolerance and
surface water has disappeared, uniformly spread aggregate of colour and size
selected by the Client and/or Engineer over surface to provide complete coverage
to depth of a single stone.
2. Embed aggregate into surface by light tamping. Float surface until embedded stone
is fully coated with mortar and surface has been brought to a true plane within
Class B tolerance. Start exposure of aggregate after matrix has hardened
sufficiently to prevent dislodgement of aggregate. Flow water, in copious quantities
without force, over surface of concrete while matrix encasing aggregate is removed
by brushing with a tine bristle brush. Continue until aggregate is uniformly exposed
but not dislodge.
3. An approved chemical retarder sprayed onto freshly floated surface may be used to
extend working time for exposure of aggregate.
I.
Slab hardener
1. Apply chemical hardener floor treatment after finishing operation to all interior floor
slabs which are exposed in finished work and elsewhere as indicated.
TECHNICAL SPECIFICATIONS
939
2. Apply chemical hardener in accord with manufacturer's printed instructions, and
after complete curing and drying of concrete surface. After final coat of chemical
hardener solution is applied and dried, remove surplus hardener by scrubbing and
mopping with water.
3. Chemical hardener: Colourless, aqueous solution containing a blend of magnesium
fluorosilicate and zinc fluorosilicate combined with a wetting agent. Provide
materials which do not react with, inhibit, or otherwise interfere with adhesives and
bonding of future floor finishes.
4. Do not place liquid floor hardener on floor areas scheduled to receive synthetic
matrix terrazzo, or setting beds for tile, terrazzo and like items.
3.9
REPAIR OF REJECTED HORIZONTAL FINISHES
Unacceptable horizontal finishes shall be replaced or corrected provided strength and
appearance are not adversely affected. High spots may be removed by grinding and/or low
spots filled with a patching compound or other remedial measures performed or permitted.

the Contract Drawings, to keep stresses within predetermined limits of symmetry
about the axes of the member.
4. Stresses shall be determined from both measured elongation and gage readings.
5. If tendons required jacking from two ends both jacking operations shall be done
simultaneously applying uniform tensioning force at each end unless otherwise
approved by the Engineer. This can be accomplished by using a single pump and
similar lengths of pressure hose to both jacks. When stressing commences it is

Cementation - Fly Ash (TDS)
One of the Market Leaders in Fly Ash Exports from India
INTRODUCTION
Fly ash is a by-product produced while burning finely ground coal in a boiler to produce electricity. It
is removed from the plant exhaust gases primarily by electrostatic precipitators or baghouses and
secondarily by scrubber systems. Physically, fly ash is a very fine, powdery material, composed mostly
of silica. Nearly all particles are spherical in shape. Fly ash is a pozzolan, a siliceous material which in
the presence of water will react with calcium hydroxide at ordinary temperatures to produce
cementitious compounds. SiO2, Al2O3, Fe2O3 and occasionally CaO are the main chemical
components present in fly ashes.
PROPORTIONING
Cementation Fly Ash is a quality assured fly ash (Full compliance to ASTM C618 Class-F / Class-C, BS
3892 Part-1, BS EN 450 and IS 3812) suitable to use in all concrete to improve the strength, stability
and long-term durability of concrete. Under normal conditions, Cementation fly ash is used to replace
15-35% of portland cement by weight. Replacement rates outside of this normal range have been
used successfully for more specialized applications. Cementation fly ash can also be added without
cement reduction to achieve desired mix characteristics. Throughout the range of fly ash percentages,
proper testing can provide proportions and material combinations yielding competitive strengths at
various age requirements.
STRENGHT, SET TIME AND PUMPNG ABILITY
Strengths of concrete properly proportioned with Cementation fly ash can be designed to closely
match those of equivalent cement-only mixes. In fact, due to the secondary pozzolanic reaction, fly ash
mixes with similar 28-day compressive strengths generally achieve 10-20% higher strengths at ages
beyond 28 days. Concrete set times utilizing 15-35% Cementation fly ash can be extended if
adjustments are not made to the mix. Proper testing can provide the materials combinations and
proportions to yield comparable set times. Due to the spherical particle shape of fly ash, the ball
bearing effect, whereby the use of fly ash in concrete lubricates the mix, results in superior pumping
ability in mixes using very angular materials or high in coarse aggregate content.
DURABILITY
Tests made in accordance with ASTM C 441 and ASTM C 1012 have shown that the use of
Cementation fly ash significantly reduces the potential for damage due to alkali-aggregate reactivity
and sulfate attack.
WATER DEMAND
Depending on the quantity of ash used, the use of Cementation fly ash consistently provides a 10% or
greater reduction in the amount of water required for a given workability. This translates directly into
increased strength and durability, reduced potential for shrinkage, reduced segregation, and most
importantly, lower permeability

UNIFORMITY
Cementation fly ash is selected by particle size to ensure the best and most consistent performance
possible. In-line sampling can detect inferior fly ash and allow operators to reject it before the fly ash
reaches the customer. This is why the carbon content in Cementation fly ash is consistently some of
the lowest found. The understanding of end product performance enhances our ability to provide
predictable and consistent product meeting customer requirements.
ENVIRONMENTAL BENEFITS
Fly ash is specifically listed in the Federal Register as a recycled material to be given preference under
the Resource Conservation and Recovery Act (RCRA). The specification and use of fly ash in concrete,
concrete and mortar products, and packaged goods highlights one of the greatest recycling efforts on
record.

weight of cement. With an addition of 15 percent, the potential exists for very strong,
brittle concrete. It increases the water demand in a concrete mix; however, dosage
rates of less than 5 percent will not typically require a water reducer. High
replacement rates will require the use of a high range water reducer.
COMPATIBILITY/ADDITION
Although SmartCare® Microsilica is compatible with other concrete admixtures, but
as known each admixture has to be added separately to the concrete using suitable
equipment.
APPLICATIONS
Effects on Air Entrainment and Air-void System of Fresh Concrete.
The dosage of air-entraining agent needed to maintain the required air content when
using SmartCare® Microsilica is slightly higher than that for conventional concrete
because of high surface area and the presence of carbon. This dosage is increased
with increasing amounts of SmartCare® Microsilica content in concrete.
Effects on Water Requirements of Fresh Concrete
SmartCare® Microsilica added to concrete by itself increases water demands, often
requiring one additional pound of water for every pound of added SmartCare®
Microsilica. This problem can be easily compensated for by using admixtures.

Technical Data Sheet
Effects on Consistency and Bleeding of Fresh Concrete.
Concrete incorporating more than 10% SmartCare® Microsilica becomes sticky; in
order to enhance workability, the initial slump should be increased. It has been found
that Silica Fume reduces bleeding because of its effect on rheological properties.
Effects on Strength of Hardened Concrete.
®
SmartCare Microsilica is used to produce very high-strength, low-permeability, and
®
chemically resistant concrete. Addition of SmartCare Microsilica by itself, with
other factors being constant, increases the concrete strength.
®
Incorporation of SmartCare Microsilica into a mixture also enables the use of a lower
water-to-cementitious-materials ratio than may have been possible otherwise The
®
modulus of rupture of concrete prepared using SmartCare Microsilica is usually
either about the same as or somewhat higher than that of conventional concrete at the
same level of compressive strength.
Effects on Freeze-thaw Durability of Hardened Concrete
Eye and skin splashes should be washed thoroughly with plenty of water and a mild
detergent.
STORAGE & DISPOSAL
®
SmartCare Microsilica is not flammable but should be stored away from acids in a
0
well ventilated place below 55 C.
®
SmartCare Microsilica is not classified as hazardous waste.
Please contact the local waste regulatory authority for guidance on methods of
disposals.
Please refer to MSDS for further details.
FIRE RISKS
®
Although SmartCare Microsilica is nonflammable but it should be stored away from
combustible material.
®
Experimental results indicated that the use of SmartCare Microsilica has no
significant influence on the production and stability of the air-void system.
Freeze-thaw testing (ASTM C 666) on Silica Fume concrete showed acceptable
results.
Effects on Permeability of Hardened Concrete
®
Addition of SmartCare Microsilica to concrete reduces its permeability. Rapid
®
chloride permeability testing conducted on SmartCare Microsilica concrete showed
that addition of 8% product significantly reduces the chloride permeability. This
reduction is primarily the result of the increased density of the matrix due to the
presence of the product.
PACKAGING
®
SmartCare Microsilica is available in 1000kg UV coated moisture resistant bags on
pallets. Bulk tankers of 25 Tons are also available upon request.

Cementation - Fly Ash (TDS)
One of the Market Leaders in Fly Ash Exports from India
INTRODUCTION
Fly ash is a by-product produced while burning finely ground coal in a boiler to produce electricity. It
is removed from the plant exhaust gases primarily by electrostatic precipitators or baghouses and
secondarily by scrubber systems. Physically, fly ash is a very fine, powdery material, composed mostly
of silica. Nearly all particles are spherical in shape. Fly ash is a pozzolan, a siliceous material which in
the presence of water will react with calcium hydroxide at ordinary temperatures to produce
cementitious compounds. SiO2, Al2O3, Fe2O3 and occasionally CaO are the main chemical
components present in fly ashes.
PROPORTIONING
Cementation Fly Ash is a quality assured fly ash (Full compliance to ASTM C618 Class-F / Class-C, BS
3892 Part-1, BS EN 450 and IS 3812) suitable to use in all concrete to improve the strength, stability
and long-term durability of concrete. Under normal conditions, Cementation fly ash is used to replace
15-35% of portland cement by weight. Replacement rates outside of this normal range have been
used successfully for more specialized applications. Cementation fly ash can also be added without
cement reduction to achieve desired mix characteristics. Throughout the range of fly ash percentages,
proper testing can provide proportions and material combinations yielding competitive strengths at
various age requirements.
STRENGHT, SET TIME AND PUMPNG ABILITY
Strengths of concrete properly proportioned with Cementation fly ash can be designed to closely
match those of equivalent cement-only mixes. In fact, due to the secondary pozzolanic reaction, fly ash
mixes with similar 28-day compressive strengths generally achieve 10-20% higher strengths at ages
beyond 28 days. Concrete set times utilizing 15-35% Cementation fly ash can be extended if
adjustments are not made to the mix. Proper testing can provide the materials combinations and
proportions to yield comparable set times. Due to the spherical particle shape of fly ash, the ball
bearing effect, whereby the use of fly ash in concrete lubricates the mix, results in superior pumping
ability in mixes using very angular materials or high in coarse aggregate content.
DURABILITY
Tests made in accordance with ASTM C 441 and ASTM C 1012 have shown that the use of
Cementation fly ash significantly reduces the potential for damage due to alkali-aggregate reactivity
and sulfate attack.
WATER DEMAND
Depending on the quantity of ash used, the use of Cementation fly ash consistently provides a 10% or
greater reduction in the amount of water required for a given workability. This translates directly into
increased strength and durability, reduced potential for shrinkage, reduced segregation, and most
importantly, lower permeability

UNIFORMITY
Cementation fly ash is selected by particle size to ensure the best and most consistent performance
possible. In-line sampling can detect inferior fly ash and allow operators to reject it before the fly ash
reaches the customer. This is why the carbon content in Cementation fly ash is consistently some of
the lowest found. The understanding of end product performance enhances our ability to provide
predictable and consistent product meeting customer requirements.
ENVIRONMENTAL BENEFITS
Fly ash is specifically listed in the Federal Register as a recycled material to be given preference under
the Resource Conservation and Recovery Act (RCRA). The specification and use of fly ash in concrete,
concrete and mortar products, and packaged goods highlights one of the greatest recycling efforts on
record.

Technical Data Sheet
PRODUCT DESCRIPTION
Parameter
®
SmartCare Microsilica is a powder mineral admixture composed of submicron
particles of silicon dioxide and manufactured as a co-product from the production of
®
silicon and ferrosilicon metal. When added to concrete, SmartCare Microsilica acts
as both micro filler, improving the physical structure by occupying the spaces
between the cement particles and as a 'pozzolan,' reacting chemically to impart far
greater strength and durability to concrete.

for use in concrete applications.
TECHNICAL SPECS / ASTM STANDARDS
ADVANTAGES
• Prevents reinforcing steel corrosion in concrete, due to its extremely low permeability
to chloride-ion intrusion and high electrical resistivity.
• Greater impermeability, barring the ingress of moisture, chemicals and other
contaminants.
• High early strengths, assuring increased efficiency and greater cost effectiveness in
the production of pre-stressed and precast concrete .
• High ultimate compressive strengths (8,000-20,000 psi), proportionate to amount of
silica fume and the water-to-cementitious ratio
• substantially greater resistance to corrosion, abrasion and erosion, chemical attack
and freeze/thaw damage

weight of cement. With an addition of 15 percent, the potential exists for very strong,
brittle concrete. It increases the water demand in a concrete mix; however, dosage
rates of less than 5 percent will not typically require a water reducer. High
replacement rates will require the use of a high range water reducer.
COMPATIBILITY/ADDITION
Although SmartCare® Microsilica is compatible with other concrete admixtures, but
as known each admixture has to be added separately to the concrete using suitable
equipment.
APPLICATIONS
Effects on Air Entrainment and Air-void System of Fresh Concrete.
The dosage of air-entraining agent needed to maintain the required air content when
using SmartCare® Microsilica is slightly higher than that for conventional concrete
because of high surface area and the presence of carbon. This dosage is increased
with increasing amounts of SmartCare® Microsilica content in concrete.
Effects on Water Requirements of Fresh Concrete
SmartCare® Microsilica added to concrete by itself increases water demands, often
requiring one additional pound of water for every pound of added SmartCare®
Microsilica. This problem can be easily compensated for by using admixtures.

Technical Data Sheet
Effects on Consistency and Bleeding of Fresh Concrete.
Concrete incorporating more than 10% SmartCare® Microsilica becomes sticky; in
order to enhance workability, the initial slump should be increased. It has been found
that Silica Fume reduces bleeding because of its effect on rheological properties.
Effects on Strength of Hardened Concrete.
®
SmartCare Microsilica is used to produce very high-strength, low-permeability, and
®
chemically resistant concrete. Addition of SmartCare Microsilica by itself, with
other factors being constant, increases the concrete strength.
®
Incorporation of SmartCare Microsilica into a mixture also enables the use of a lower
water-to-cementitious-materials ratio than may have been possible otherwise The
®
modulus of rupture of concrete prepared using SmartCare Microsilica is usually
either about the same as or somewhat higher than that of conventional concrete at the
same level of compressive strength.
Effects on Freeze-thaw Durability of Hardened Concrete
Eye and skin splashes should be washed thoroughly with plenty of water and a mild
detergent.
STORAGE & DISPOSAL
®
SmartCare Microsilica is not flammable but should be stored away from acids in a
0
well ventilated place below 55 C.
®
SmartCare Microsilica is not classified as hazardous waste.
Please contact the local waste regulatory authority for guidance on methods of
disposals.
Please refer to MSDS for further details.
FIRE RISKS
®
Although SmartCare Microsilica is nonflammable but it should be stored away from
combustible material.
®
Experimental results indicated that the use of SmartCare Microsilica has no
significant influence on the production and stability of the air-void system.
Freeze-thaw testing (ASTM C 666) on Silica Fume concrete showed acceptable
results.
Effects on Permeability of Hardened Concrete
®
Addition of SmartCare Microsilica to concrete reduces its permeability. Rapid
®
chloride permeability testing conducted on SmartCare Microsilica concrete showed
that addition of 8% product significantly reduces the chloride permeability. This
reduction is primarily the result of the increased density of the matrix due to the
presence of the product.
PACKAGING
®
SmartCare Microsilica is available in 1000kg UV coated moisture resistant bags on
pallets. Bulk tankers of 25 Tons are also available upon request.
