It is used to measure the drying shrinkage of
concrete autoclave expansion of Portland cement and potential expansive
reactivity of cement aggregate combinations in mortar bars during storage on
The instrument consists of a channeled base over which two vertical pillars
are fixed. An adjustable cross plate is at the top. A dial gauge, reading to
.002mm x 12mm. can be fixed to the top cross plate. The plunger end of the
dial gauge can be located upon a 6.5mm dia ball or other reference point
cemented in the specimen. On the base there is a similar recessed seating in
which can be placed a second ball or reference pint in the specimen.
Complete with a stainless steel standardization bar with insulated grip and
with 6.5mm dia. balls mounted in the ends. The unit can be supplied with a
.0001inch x 1/2inch x 1/2inch dial gauge at extra cost if indicated at the
time of placing the order.
This apparatus is used to test the flow of water
through the cement concrete specimen, which in turn checks durability of
mix. It is available in 1- 3 nos. of cells.
As Per IS Standard 8142
Penetrometer consists of cylindrical spring housing with plunger attached
to the top of the spring. Penetration needle is attached to the other end of
the spring housing. The plunger is graduated in 1 kg divisions, to maximum
capacity of 60 kg, which can be read with respect to the top end of the
spring housing. A set of six needle points with areas of 645, 323, 161, 65,
32 and 16 mm2 are provided.
Supplied complete in a wooden carrying case.
Slump Test Apparatus
Conforming to BIS -7320. This apparatus used for the
determination of workability of concrete where nominal size of aggregate
does not exceed 38 mm. The apparatus comprises of a slump cone with foot
pieces fitted on a base with wing bolts. A swivel carrying handle fitted
with the base also serves as a datem for measuring the slump, when moved
into vertical position perpendicular to the base. A graduated tamping rod is
used both for compacting the specimen as well as measuring the slump of
The slump cone is filled with freshly mixed concrete and is tamped with a
tamping bar in three or four layers. The top of the concrete is leveled off
with the top of the slump cone, the cone is lifted vertically up and the
slump of the sample is immediately measured.
Proper compaction of cement concrete while casting
specimens for compression testing is desirable to achieve a better and more
consistent mixture. Vibrating table is ideally suited for this purpose. The
table top is 1000 mm x 1000 mm and has stops along its edges to prevent
moulds from sliding off the table during operation.
The maximum load capacity is 250 kg. The variable pitch pulley arrangement
permits the frequency to be varied steplessly between 600 cycles / sec. and
430 cycles / sec. Suitable for operation 415 volts, 3 phase. 50 Hz. A.C.
Air Entrainment Meter
AS PER I.S. 9799
Capacity - 0.005 cum. For concrete containing nominal maximum size of
aggregate of 38 mm. The apparatus consists of a measuring bowl of 0.005 cm
capacity. A flanged conical cover assembly fits over the bowl and can be
sealed with clamps keeping a rubber gasket in between. A water inlet valve
with a spray tube and an air bleed valve are fitted on the conical cover
assembly. A Perspex cylindrical graduated stand pipe is fitted on the
conical cover assembly. A pressure gauge is mounted on the top of the stand
pipe. A hand pump is provided for the application of pressure.
Supplied complete with a calibrating cylinder, a rubber mallet, a measure
and a tamping rod.
Air Permeability Apparatus
It is used for determination of fineness of cements,
pozzolanss and other powdery material in terms of specific surface, which is
expressed as total surface area in sq. cm. per gram of material under test.
The apparatus comprises the followings:-
- Standard Permeability cell made of brass, 12.5 mm. inside dia with
one perforated metal disc and one plunger.
- A U - tube glass manometer with rubber coupling for permeability
cell, mounted on a wooden stand.
- Latex rubber tubing, 30 cm. long.
- 250 ml. Dibutylphthalate liquid
Vicat apparatus is used to confirm the water
quantity required to produce the cement paste of standard consistancy. Its
frame carry consistancy plunger of 10mm diameter.
Compression Testing Machine (Electrical)
The machine embodies a hydraulic system designed to
meet the requirement of IS 516-1959 for compression tests on concrete cubes
up to 15cm X 15cm X 15cm and also concrete cylinders up to 30cm height.
Loading Unit- The hydraulic jack is fixed to base. The upper platen
has got a self-aligning action and is attached to a screw which passes
through the cross-head plate, and can be raised or lowered for initial
clearance adjustment. The lower platen rests on the jack ram and is
positioned with the help of a centering pin. Loading is accomplished by the
upward movement of the lower platen. A dust cover is provided on the jack to
prevent any dust from going into the cylinder. A spacer with a centering
locating pin is provided to test small specimens. The lower and upper
platens of the machine are hardened, ground and polished. Guidelines are
marked on the lower platen to keep the specimen coaxial with the hydraulic
Pumping Unit- The motorized pumping unit, which is housed in an
elegant console, is of double plunger type and is driven by a single phase
220 Volts 50 cycles electric motor. The pumping unit is a separate unit
connected to the jack by means of a rubber hose pipe. A junction box is
suitably fixed to connect the motor to the mains through a push button
starter. The pumping unit is fitted with a 20cm dia dial hydraulic pressure
gauge calibrated by N.C.B.M. A max red pointer is provided to facilitate
taking readings after failure of the specimen. The pressure gauge is fixed
at an angle for easy readability. The machine is fitted with a hand wheel
control which enables the rate of application of load to be varied. "The
machine is equipped with facilities for hand pumping in case of power
failure." The electric pumping unit is fixed with a micro-switch to
switch-off the motor automatically as the load on the machine approaches the
rated capacity. Relays are incorporated in the pumping unit so that in case
of breakdown of power supply, the motor will stop and will not re-start
unless the starting switch is operated.
