Tenders Received ‘will be published on the notice board at the University of Malta,
Procurement Directorate, Administration Building, 2nd Floor; and shall also be
available
to
view
on
the
University’s
website,
www.um.edu.mt/procurement/service/tender under the respective tender page.
27.2
At the tender opening, the tenderers' names, the tender prices, variants, written
notification of alterations and withdrawals, the presence of the requisite tender
guarantee and any other information the University of Malta may consider appropriate
will be published.
27.3

27.4

be taken into consideration during the analysis and evaluation of tenders.
28. Secrecy of the Procedure
28.1
After the opening of the tenders, no information about the examination,
clarification, evaluation or comparison of tenders or decisions about the contract
award may be disclosed before the notification of award.
28.2
Information concerning checking, explanation, opinions and comparison of tenders and
recommendations concerning the award of contract, may not be disclosed to tenderers
or any other person not officially involved in the process unless otherwise permitted or
required by law.
28.3
Any attempt by a tenderer to approach any member of the Evaluation
Committee/University of Malta directly during the evaluation period will be considered
legitimate grounds for disqualifying his tender.
29. Clarification of Tenders
29.1
When checking and comparing tenders, the evaluation committee may, after obtaining
approval from the Departmental Contracts Committee, ask a tenderer to clarify any
aspect of his tender.
29.2
Such requests and the responses to them must be made by e-mail or fax. They may in
no circumstances alter or try to change the price or content of the tender, except to
correct arithmetical errors discovered by the evaluation committee when analysing
tenders, in accordance with Clause 31.
30. Tender Evaluation Process
30.1
The following should be read in conjunction with Clause 27.
30.2
Part 1: Administrative Compliance
The Evaluation Committee will check the compliance of tenders with the instructions
given in the tender document, and in particular the documentation submitted in
respect of Clause 16.
The Evaluation Committee shall, after having obtained approval by the Department
Contracts Committee, request rectifications in respect of incomplete/non-submitted
information pertinent to the documentation as outlined in sub-Clause 16.1(a), 16.1(b),
and 16.1(c) of these Instructions to Tenderers. Such rectification/s must be submitted
within two (2) working days from notification, and will be subject to a non-refundable
administrative penalty of €50: failure to comply shall result in the tender offer not
Page 13
being considered any further. No rectification shall be allowed in respect of the
documentation as outlined in sub-Clause 16.1 (d), 16.1(e), and 16.1(f) of these
Instructions to Tenderers. Only clarifications on the submitted information in respect of
the latter may be eventually requested.
30.3
Part 2: Eligibility and Selection Compliance
Tenders which have been considered administratively compliant shall be evaluated for
admissibility as outlined below:
(i) Eligibility Criteria
Tender Form (Volume 1, Section 2)
(ii) Selection Criteria
Evidence of technical capacity
30.4
Part 3: Technical Compliance
At this step of the evaluation process, the Evaluation Committee will analyse the
administratively-compliant tenders‘ technical conformity in relation to the technical
specifications (Volume 3, and the documentation requested by the Contracting
Authority as per sub-Clause 16(e)), classifying them technically compliant or noncompliant.
Tenders who are deemed to be provisionally technically compliant through the
evaluation of their technical offer (especially the specifications) shall be requested to
submit samples so that the Evaluation Committee will corroborate the technical
compliance of the offers received.
30.5
Part 4. Financial Evaluation
The financial offers for tenders which were not eliminated during the technical
evaluation (i.e., those found to be technically compliant) will be evaluated.
The Evaluation Committee will check that the financial offers contain no arithmetical
errors as outlined in Clause 31. [If the tender procedure contains several lots, financial
offers are compared for each lot.] The financial evaluation will have to identify the
best financial offer [for each lot].
31. Correction of Arithmetical Errors
31.1
Admissible tenders will be checked for arithmetical errors by the Evaluation
Committee. Errors will be corrected as follows:
(a) where there is a discrepancy between amounts in figures and in words, the
amount in words will prevail;
(b) where there is a discrepancy between a unit price and the total amount
derived from the multiplication of the unit price and the quantity, the unit
price as quoted will prevail.
31.2
The amount stated in the tender will be adjusted by the Evaluation Committee in the
event of error, and the tenderer will be bound by that adjusted amount. In this regard,
the Evaluation Committee shall seek the prior approval of the General Contracts
Committee to communicate the revised price to the tenderer. If the tenderer does not
accept the adjustment, his tender will be rejected and his tender guarantee forfeited.
31.3
When analysing the tender, the evaluation committee will determine the final tender
price after adjusting it on the basis of Clause 31.1.
F. CONTRACT AWARD
Page 14
32. Criteria for Award
32.1
The sole award criterion will be the price. The contract will be awarded to the
cheapest priced tender satisfying the administrative and technical criteria.
33. Right Of The University of Malta To Accept Or Reject Any Tender
33.1
The University of Malta reserves the right to accept or reject any tender and/or to
cancel the whole tender procedure and reject all tenders. The University of Malta
reserves the right to initiate a new invitation to tender.
33.2
The University of Malta reserves the right to conclude the contract with the successful
tenderer within the limits of the funds available. It can decide to reduce the scope of
works or to ask for a discount from the cheapest compliant tenderer.
33.3
In the event of a tender procedure's cancellation, tenderers will be notified by the
University of Malta. If the tender procedure is cancelled before the outer envelope of
any tender has been opened, the sealed envelopes will be returned, unopened, to the
tenderers.
33.4
Cancellation may occur where:
(a) the tender procedure has been unsuccessful, namely where no qualitatively or
financially worthwhile tender has been received or there has been no response
at all;
(b) the economic or technical parameters of the project have been fundamentally
altered;
(c) exceptional circumstances or force majeure render normal performance of the
project impossible;
(d) all technically compliant tenders exceed the financial resources available;
(e) there have been irregularities in the procedure, in particular where these have
prevented fair competition.
In no circumstances will the University of Malta be liable for damages, whatever
their nature (in particular damages for loss of profits) or relationship to the
cancellation of a tender, even if the University of Malta has been advised of the
possibility of damages. The publication of a contract notice does not commit the
University of Malta to implement the programme or project announced.
34. Notification of Award, Contract Clarifications
34.1
Prior to the expiration of the period of validity of tenders, the University of Malta will
notify the successful tenderer, in writing, that his tender has been recommended for
award by the General Contracts Committee, pending any appeal being lodged in terms
of Part XIII of the Public Procurement Regulations (being reproduced in Volume 1,
Section 6).
34.2
Unsuccessful bidders shall be notified with the outcome of the evaluation process, and
will be provided the following information:
(i) the criteria for award;
(ii) the name of the successful tenderer;
(iii) the recommended price of the successful bidder;
(iv) the reasons why the tenderer did not meet the technical specifications/notification
that the offer was not the cheapest (if applicable);
(v) the deadline for filing a notice of objection (appeal);
(vi) the deposit required if lodging an appeal.
34.3
The recommendations of the Evaluation Committee and the Department Contracts
Committee shall be published on the Notice Board of the University of Malta,
Procurement Directorate, Administration Building, 2 nd Floor, and published online on
the University of Malta‘s website, www.um.edu.mt/procurement/service/tender under
the respective tender page.
Page 15
35. Contract Signing and Performance Guarantee
35.1
After the lapse of the appeals period, and pending that no objections have been
received and/or upheld, the successful tenderer may be invited to clarify certain
contractual questions raised therein. Such clarification will be confined to issues that
had no direct bearing on the choice of the successful tender. The outcome of any such
clarifications will be set out in a Memorandum of Understanding, to be signed by both
parties and incorporated into the letter of acceptance.
35.2
Within 7 calendar days of receiving the letter of acceptance (against acknowledgment
of receipt) from the University of Malta, the successful tenderer will sign a copy of the
Letter of Acceptance and date the Letter of Acceptance and return it to the University
of Malta with the performance guarantee and the Financial Identification Form (if
applicable).
35.3
Before the University of Malta sends the Letter of Acceptance to the successful
tenderer, the successful tenderer may be requested to provide the documentary proof
or statements required to show that it does not fall into any of the exclusion situations
listed in Clause 7 of the Tender Form (Volume 1, Section 2). The above mentioned
documents must be submitted by every member of a Joint Venture/Consortium (if
applicable).
35.4
If the selected tenderer fails to sign and return the copy of the Letter of Acceptance,
other required documentation, and any guarantees required within the prescribed 7
calendar days, the University of Malta may consider the acceptance of the tender to be
cancelled without prejudice to the University of Malta's right to seize the guarantee,
claim compensation or pursue any other remedy in respect of such failure, and the
successful tenderer will have no claim whatsoever on the University of Malta.
The tenderer whose tender has been evaluated as [second cheapest/second most
economically advantageous] may be recommended for award, and so on and so forth.
35.5
Only the signed Letter of Acceptance will constitute an official commitment on the
part of the University of Malta, and activities may not begin until the contract has been
signed both by the University of Malta and the successful tenderer.
35.6
Tender guarantees (bid bonds) provided by tenderers who have not been selected shall
be released within 30 calendar days from the signing of the contract. The tender
guarantee of the successful tenderer shall be released on the signing of the contract,
and on submission of a valid performance guarantee.
35.7
The performance guarantee referred to in the General Conditions is set at 10% of the
amount of the contract and must be presented in the form specified in Volume 2,
Section 4, to the tender document the performance guarantee shall be released within
30 days of the signing of the Final Statement of Account (Final Bill), unless the Special
Conditions provide otherwise.
36. Commencement of Works (Order To Start Works)
36.1
Following the signing of the contract by both parties, the Supervisor will issue a written
notice of commencement of the works in accordance with the General Conditions, as
specified by the Special Conditions.
36.2
The Contractor must inform the University of Malta's representative by return that he
has received the notice.
G. MISCELLANEOUS

37.1
Any attempt by a candidate or tenderer to obtain confidential information, enter into
unlawful agreements with competitors or influence the committee or the University of
Malta during the process of examining, clarifying, evaluating and comparing tenders
Page 16
will lead to the rejection of his candidacy or tender and may result in administrative
penalties.
37.2
Without the University of Malta's prior written authorisation, the Contractor and his
staff or any other company with which the Contractor is associated or linked may not,
even on an ancillary or sub-contracting basis, supply other services, carry out works or
supply equipment for the project. This prohibition also applies to any other
programmes or projects that could, owing to the nature of the contract, give rise to a
conflict of interest on the part of the Contractor.
37.3
When putting forward a candidacy or tender, the candidate or tenderer must declare
that he is affected by no potential conflict of interest, and that he has no particular
link with other tenderers or parties involved in the project.
37.4
The Contractor must at all time act impartially and as a faithful adviser in accordance
with the code of conduct of his profession. He must refrain from making public
statements about the project or services without the Contracting Authority's prior
approval. He may not commit the Contracting Authority in any way without its prior
written consent.
37.5
For the duration of the contract, the Contractor and his staff must respect human
rights and undertake not to offend the political, cultural and religious morals of Malta.
37.6

provided for therein. The Contractor and his staff must not exercise any activity or
receive any advantage inconsistent with their obligations to the Contracting Authority.

or presented by them during the execution of the contract.
37.9
The Contractor shall refrain from any relationship likely to compromise his
independence or that of his staff. If the Contractor ceases to be independent, the
University of Malta may, regardless of injury, terminate the contract without further
notice and without the Contractor having any claim to compensation.
37.10
The tender(s) concerned will be rejected or the contract terminated if it emerges that
the award or execution of a contract has given rise to unusual commercial expenses.
Such unusual commercial expenses are commissions not mentioned in the main contract
or not stemming from a properly concluded contract referring to the main contract,
commissions not paid in return for any actual and legitimate service, commissions
remitted to a tax haven, commissions paid to a recipient who is not clearly identified

company.

University of Malta in terms of the Freedom of Information Act (Cap. 496 of the Laws of
Malta). The University of Malta, prior to disclosure of any information to a third party
in relations to any provisions of this contract which have not yet been made public,

Page 17
terms of the Act.
39. Gender Equality

ensure the application of the principle of gender equality and shall thus ‘inter alia‘
refrain from discriminating on the grounds of gender, marital status or family
responsibilities. Tenderers are to ensure that these principles are manifest in the
organigram of the company where the principles aforementioned, including the
selection criteria for access to all jobs or posts, at all levels of the occupation
hierarchy are amply proven. In this document words importing one gender shall also

If ready mixed concrete is permitted by the Engineer-in-Charge, the concrete shall
comply with the requirements of this specification and shall additionally conform to the
requirements of the B.R.M.C.A. publication 'Codes for Ready Mixed Concrete' May 1975. If
anomalies arise between this publication and BS 5328, the British Standard will take
precedence.
e)
Reinforcement
i.
Preparation of Reinforcement
The reinforcement is to be free from oil, paint, mild scale, excessive rust or coating
of any character, which would tend to destroy its adhesive bond with the concrete.
ii.
Bending of Reinforcement
-
All rods shall be bent cold in accordance with BS 4466.
Rods showing signs of cracking or brittleness following bending, shall not be used in
the Works.
-
No welding of rods will be permitted, except tack or positional welding between
plain mild steel rods crossing approximately at right angles so as to fix them in
position, such welding of high tensile or work-hardened mild steel rods will not be
allowed except in fabric to BS 4483.
-
Care is to be taken to ensure that the overall depth of bent rods and the overall size
of links are accurate, and that the rods do not unwind after they are bent.
iii.
Fixing of Reinforcement
-
Adequate temporary spacers, chairs and binding wire shall be provided to maintain
the steel in correct position. Binding wire is to be thoroughly annealed 1.5mm
Page 57
diameter soft iron wire. These items shall be deemed to be included in the rates for
fixing.
-
Covers to the steel reinforcement shall be properly maintained.
-
Fabric reinforcement shall be lapped 400mm in each direction and tied at 300mm
centres along each joint, or as shown on drawings.
-
On no account is any reinforcement to be left out for insertion into web concrete
during the progress of concreting, and in no case may any portion of the concrete be
put in position and allowed to set in order to act as a base upon which to set up any
of the reinforcement for the member.
iv.
Inspection of fixed Reinforcement
When the reinforcement is in position ready for concreting, the Contractor must
notify the Architect who is to arrange for it to be checked before any of it is
covered up with concrete. Such checking will not relieve the Contractor from any of
his responsibilities under the Contract.
3.7.5 Execution
a)
Shuttering
i.
The Contractor shall be entirely responsible for the design, erection and safe
removal of all shuttering.
ii.
Faces in contact with concrete shall be free from adhering grout, projecting
nails, splits, or other defects. Joints shall be sufficiently tight to prevent the
leakage of cement grout and to avoid formation of fins or other blemishes. Faulty
joints shall be caulked.
iii.
Surface finishes on shuttering shall be as shown on the Drawing and shall
conform to 6.10 of BS 8110.
Shuttering faces shall be treated with the minimum of mould oil necessary to
obtain a clean release.
All shuttering be removed by gradual easing without such shock or vibration
as would damage the concrete and in no circumstances shall the shutters be struck
until the concrete reaches sufficient strength to withstand any stresses to which it
may be subjected.
b)
Casting of Concrete
i.
All shuttering must be thoroughly cleaned out with compressed air
immediately before deposition of concrete ; all concrete, must be placed in position
immediately after mixing and every subsequent operation necessary to complete the
finished concrete must follow on without delay, and must be all finished before the
concrete starts to harden. Usually, with ordinary cement, all work upon the
concrete should be completed within an hour after mixing.
ii.
All shuttering and reinforcement shall be clean and free from water,
immediately before the placing of concrete. Any accumulation of set concrete or
Page 58
grout on the reinforcement shall be removed by wire brushing before concrete is
placed.
iii.
Concrete shall not be placed in any part of the works until the Architect's
approval being given. If concreting is not started with 24 hours of approval being
given, approval shall again be obtained from the Architect.

constituent materials does not occur.
ii.
Concrete is not to be distributed to its final position by means of vibration.
iii.
Care must be taken not to move reinforcement during concreting. Shaking of
reinforcement to assist the placing of concrete will not be permitted.
iv.
Care must be taken to ensure that any rods which project from set or
partially set concrete are not moved or jarred.
v.
Concreting must be carried on continuously up to construction joints. All
construction joints must be carefully arranged in approved positions where they will
have the least effect upon the strength of the structure, and any pauses in the work
(such as for meals) must be arranged as far as possible to occur at approved
construction joints. No slips will be permitted in connection with construction joints
in concrete, and all such joints must be made against a rigidly fixed board having
one or more splayed battens fixed longitudinally thereto, (either vertically or
horizontally as ordered) so that the joint is on a surface in a plane normal to it for
the next section of work, or in such other manner as directed. Great care is to be
taken to ensure by thoroughly ramming that the new concrete bonds solidly with the
old.
vi.
In all cases, where work has to be recommenced on a surface which has
hardened, all laitance, loose stones and debris must be removed therefrom, the
surface must be well hacked rough, swept clean and thoroughly wetted. In all cases,
great care must be taken to ensure by thoroughly ramming that the new concrete
bonds solidly with the old.
d)
Transporting of Concrete
The concrete shall be discharged from the mixer and transported to the works by
means which shall prevent adulteration, segregation or loss of ingredients, and so as
to ensure that the concrete is of the required workability at the point and time of
placing. Segregated concrete will be rejected.
Page 59
e)
Compaction of Concrete
i.
All concrete is to be consolidated by vibration to ensure that the concrete is
worked into every interstice between and around the reinforcement so as to ensure
a compact mass without voids and of the greatest possible density throughout.
ii.
Wherever possible, vibration is to be carried out with immersion vibrators
which are to be applied for short duration sufficiently frequently to consolidate the
concrete effectively. Points of vibration are in no case to be farther apart than
500mm. Immersion vibrators are to be totally immersed in the concrete and
withdrawn slowly, the maximum speed of withdrawal is not to exceed 75mm per
second. Vibrators are not to be allowed to rest against, or come into contact with
reinforcement of the faces or formwork.
f)
Curing and Protection of Concrete
i.
Minimum periods shall be indicated in Table 6.5 of BS 8110 : Part 1:1985 or
EN Equivalent.
ii.
Traffic or loading must not be allowed on the concrete is, on the opinion of
the Engineer-in-Charge, sufficiently matured, and in no case, shall traffic or loading
be of such magnitude as to cause deflection or other movement in the formwork or
damage to the concrete member.
iii.
Concrete must be protected during hardening from the harmful effects to the
weather, or running water. The protection shall be applied immediately after
completion of placing by one or more of the following methods :
1.
By covering with a layer of sand, sacking, canvas, hessian, straw mats or
similar absorbent materials and keeping constantly wet for 72 hours.

Page 64
3.9.3 Repairs - General
Repair(s) of concrete, including reinforced concrete, to restore the structure to an
acceptable condition shall comply with EU Directive 89/106/EEC as implemented by
the relevant directive.
This Specification covers a number of deterioration mechanisms, namely:
Chloride-induced corrosion of steel
Carbonation-induced corrosion of steel
Chemical attack
Alkali-aggregate reaction
Fire damage
Abrasion, impact, erosion, cavitation
Structural damage
Note1:
Reasons for deterioration of structures involve complex interactions
between natural processes, service environment, materials properties,
and quality in design, detailing and construction.
Note2:
Deterioration is controlled primarily by three transport mechanisms:
diffusion,
permeation (by pressurehead) and capillary suction. It is the
susceptibility of the substrate to these mechanisms, and the severity of
the environment, that controls the rate of deterioration and demand for
repair.
3.9.4 Repair Processes
The condition of the structure, including the extent and severity of defects. is
normally established by the FTS Architect and communicated to the Contractor.
The Contractor may however be instructed to establish the state and condition of
the structure, in which case a planned regime of inspection and testing of the
structure by suitably experienced and qualified engineers shall be undertaken.
In particular, it is important to establish the cause or causes of deterioration so that
the repair strategy to be applied is appropriate for both rectifying the existing
defects and resisting future deterioration.
3.9.5 Planning of Repairs
The Contractor shall submit a detailed Repair Methodology comprising the following:
(a) Assessment of the condition of the structure
(b) Identification of the causes of deterioration
(c) Deciding the Objectives of protection and repair
(d) Selection of the appropriate principles for protection and repair
(e) Selection of methods
Page 65
(f) Definition of properties of products and systems to be used
(g) Specification of maintenance requirements following protection and
repair.
3.9.6 Method(s) of Investigation
There are various methods for investigating the condition of a structure. These
preferred methods are those presented by the Concrete Society (UK), British
Standards Codes of Practice and CEN Standards.
A research report compiled by Mott Macdonald (2003) for the HSE (UK), ―Field
Studies of the Effectiveness of Concrete Repairs‖ is available for guidance at
www.hse.gov.uk.
The investigation process may involve a preliminary visual survey, followed by more
detailed inspection and testing to determine the cause and general extent of
deterioration. Depending on these findings, further investigation and testing may be
required to identify specific boundaries of deterioration or potential deterioration.
3.9.7 Repair Methods to EN 1504
The repair methods and processes shall be carried out as indicated in EN 1504-9.
(This standard identifies the key stages in planning and executing the repairs. The
requirements of these stages are further described in the informative sections
(Annex B) of EN 1504-9, supporting the main text). The key stages include
establishing the condition of the structure, the form of construction and the
exposure and service environments, assessment of defects, planning of possible
repair options, detailed design of selected repair works, execution of the repairs
and acceptance of the works. These stages include the following:

Repair materials should be selected to provide the best and most cost-effective
combination/s that:
i. Restore structural integrity
ii. Arrest deterioration
iii. Prevent future deterioration
iv. Restore original profile
v. Restore aesthetic appearance
3.9.9 Conventional Repair Materials and Systems
This Specification deals with patch repair materials for concrete substrates (There
are many variables in repair materials and systems. These include the technique or
form of repairs, material composition, method of application, fresh properties and
set properties).
For the purposes of this Specification, patch repairs are defined as those applied to
substrate concrete and contained within an element, and are typically less than 1m 2
in area and less than 100mm in depth. However, patch repair systems may include
additional components such as bonding and finishing coats.
A full repair system normally includes:
a.
Protective Coating for reinforcing steel
b.
Bonding agent
c.
Repair mortar(s)
d.
Fairing coat (to level irregularities between the repair and the retained area
of un-repaired
concrete)

(i)
Inspection and diagnosis
(ii)
Concrete breakout
(iii)
Cleaning and supplementing existing reinforcing bar
(iv)
Coatings for reinforcing bar
(v)
Bonding aid/chloride barrier
(vi)

(vii) Repair concrete and mortar
(viii) Curing
(ix)
Concrete coating
(x)
Supervision and quality control
The inspection and diagnosis step will allow the repair strategy to be planned and
areas for repair to be marked or otherwise identified. The remaining stages are
generally described in method statements supplied by the manufacturer of the
proprietary material.
Concrete can be broken out using a variety of methods. Good practice dictates that
the perimeter of the repair is saw-cut to prevent feather-edges, and that break-out
equipment and techniques cause minimal damage to the substrate. Bars should be
fully exposed and cleaned by abrasion or blasting. Where bars are severely
damaged, they shall generally be replaced with new overlapping lengths.
Reinforcement within a break out shall be coated to protect from ongoing corrosion.
The coatings shall isolate the steel from the surrounding material and minimise
exposure to water, oxygen and chloride ions. The surface of the break-out shall be
prepared to minimise fracture and loose material. The surface shall then be cleaned
to remove dust and other debris. It may be coated with a bonding primer to increase
the adhesion with the main repair material. This latter is applied , worked and
compacted to provide a dense, homogenous infill with continuous bond to the
substrate, devoid of cracks, partings, cavities and voids. The surface is finished so as
to be flush with the surrounding concrete, or a fairing coat may be used to achieve a
smooth finished surface.
A curing process is applied to the material to minimise the detrimental effects of
drying and exposure to the environment whilst the material is still immature.
Overcoating of the repaired area may then be carried out. This may be for cosmetic
reasons or for additional protection using a barrier designed to reduce the ingress of
water, ions, oxygen and carbon dioxide.
3.9.14
Repairs using Flowable Materials
Repairs using flowable materials involve the preparation of the substrate in a similar
way to that described above for hand placed techniques. However, after
preparation, formwork is constructed in the area that will receive the material, and
an access for delivery is created. A fluid repair material can then be poured into the
shutter through a funnel and pipe. This provides benefits in the volume of repair
that can be effected at a single time, and may be the best technique in the
Page 69
presence of congested reinforcement or a complex or inaccessible substrate. Curing
processes may be applied to exposed surfaces of a flowable material after removal
of the formwork.
3.9.15
Sprayed Concrete
Sprayed concrete is composed of a cementitious binder, aggregates, water and
additives that are formulated to be projected, or sprayed, from a nozzle and to
form a cohesive, durable material upon impact with the target substrate. Sprayed
concrete repairs are particularly appropriate for larger repair volumes, such as large
surface areas of repair or multiple repair sites situated close together.
3.9.16
Flood Grouting
Flood grouting involves pouring a highly fluid grout through a pre-placed single sized
aggregate matrix. The fluid then sets and binds the aggregate matrix to form a solid
material.
3.9.17
Electromechnical Repair techniques
Electromechanical repair techniques include the following;
(i) Cathodic protection (CP)
(ii) Re-alkalisation
(iii) Chloride removal
Corrosion inhibiting systems rely on the action of materials on the reinforcement to
inhibit ongoing corrosion.
Corrosion inhibitors
Electrochemical techniques
Inorganic Anodic Inhibitors
Cathodic Protection (CP)
Organic Mixed Inhibitors
Re-alkalisation
Vapour Phase or Volatile
Inhibitors
Electrochemical Chloride
Extraction (ECE)
3.9.18
Re-Alkalisation
Re-alkalisation is a method where temporary current is applied to an anode (fixed to
the exterior of the concrete) and an internal cathode (the steel reinforcement). The
positive ions in the electrolyte (an alkaline solution, commonly of sodium carbonate)
move towards the reinforcement whilst hydroxyl ions are produced at the steel
reinforcement due to the reduction of water. The method is best applied to
carbonated concrete where the material is still sound. The re-alkalisation treatment
is typically applied for 3-5 days, and is intended to generate an environment of
sufficient alkalinity at the reinforcement to prevent de-passivation and subsequent
corrosion of the reinforcing steel.
3.9.19
Chloride Extraction
Chloride extraction relies on similar mechanisms to the re-alkalisation process; it is
another temporary process intended to provide long-term solutions to problems of
chloride ingress in sound concrete. It has sometimes been referred to as
desalination. An electrical current is set up in the reinforced concrete, with an
externally applied anode and the reinforcing steel once more playing the role of the
cathode. Negatively charged chloride ions are attracted by the positive anode and
Page 70
repelled by the cathode (steel). The net result is that chloride is either removed
from the concrete into the electrolyte, or at the minimum, taken further away from
reinforcing steel where it would have accelerated the corrosion process. Hydroxyl
ions are generated at the steel. Three to five weeks are required for this process to
take place and electrolytes are commonly water or saturated calcium hydroxide.
3.9.20
Cathodic Protection
Cathodic protection is an electro-chemical technique that has traditionally been
used as long-term form of protection to prevent the corrosion of steel.
The principle is similar to that for chloride extraction, with an electrical current set
up in the reinforced concrete so that the steel is cathodic, but with a much smaller
current. There are two main types; impressed current systems use a conductive
anode overlay, typically over the external surface of the concrete, with an external
power source, whilst sacrificial anode systems use discreet, independent anode
units normally buried within the concrete.
3.9.21
Methods of Test - General
The evaluation of conformity of products and systems for the surface protection of
