DIFFERENT APPARATUS OR INSTRUMENT AND
EQUIPMENT USED IN TESTING OF MATERIALS
APPARTUS / EQUIPMENT
1. CYLNDRICAL MOLD

2. SLUMP TEST APPARATUS


3. SWCC MEASURING INSTRUMENT

DEFINITION / FUNCTION
Made of steel, suitable for
preparation of test cylinders.
Forms standard concrete and
mortar cylinder samples.
The slump test indicates the
consistency of concrete in
different batches. The
concrete slumps reveal
information about concrete’s
workability and quality.
Parts: mould, base plate,
tamping rod.
It is used to forecast soil water
storage and determine the
hydraulic and mechanical
behavior of unsaturated soils.
Direct measuring is timeconsuming and difficult.
4. WP4C DEWPOINT POTENTIAMETER

The WP4C determines the
relative humidity of the air
above a sample in a sealed
chamber to determine water
potential.
5. GRADUATED BEAKERS

It is used for accurately
measuring the volume of
liquids and is suitable for
various applications,
including mixing and
transferring liquids
6. SET OF SIEVES

Gradation is the most
common use of sieve
analysis, and it distinguished
the different qualities of soil
mechanics, aggregates, and
other materials used in the
construction of various
structures.
7. PYKNOMETER BOTTLES

An equipment used in
laboratories to determine the
volume or density of a solid or
liquid element. As a result, it is
possible to determine the
temperature of said element.
8. TRIPPLE BEAM BALANCE

The triple beam balance is a
precise instrument used for
measuring mass. The varying
sizes of the beams
correspond to the different
weights and scale readings
that each beam can
measure.
9. UNIVERSAL MACHINE TESTING
COMPRESSOR

The goal of the machine is to
see if the material is strong
and durable enough. The
machine can pull, compress,
bend, or stretch material past
its breaking point and it’s
employed in the industrial
world to see if goods are up
to the purpose they were built
for.
10. SPECFIC GRAVITY TEST MACHINE

Concrete’s strength and
water absorption capacity
are heavily influenced by
aggregate specific gravity
and porosity.
It is a measurement of
aggregate density, making it
the most important indicator
of quality and strength. The
higher the specific gravity,
the more powerful it is.

11. CRUSHING TEST MACHINE FOR
AGGREGATES

When a coarse aggregate is
tested for crushing value, a
relative measure is given of its
strength under gradual cyclic
compressions. Good
pavement material should be
able to withstand crushing
under rollers and traffic loads,
i.e. Lower crushing values
indicate a lower crushing
fraction and would give a
better result, longer service
life as well as economic
value.
12. IMPACT TESTING MACHINE FOR
AGGREGATES

It refers to an aggregate’s
ability to withstand a sudden
impact or shock load.
13. DORRY ABRASION TESTING MACHINE

It determines whether
aggregates are resistant to
abrasion. Road-surface
aggregates that have a low
abrasion resistance will
quickly lose the texture depth
required for high-speed
skidding resistance.
14. LIQUID LIMIT DEVICE

The liquid limit of soil is an
important property that tells
us how the soil behaves. It is
like a special point where the
soil changes from being soft
and moldable to becoming
like a liquid.
15. ANALYTICAL BALANCE

An analytical balance is
a highly accurate laboratory
balance designed to
determine an object’s mass
precisely. The objects could
be solid, liquid, granular
substances, or powders.
