The machine consists of a hand frame. The lower platen has two rollers the distance between which is adjustable For 150 mm x 150 mm x 700 mm beam, the center distance between rollers is 600 mm, while it is 400 mm for beams of size 100mm x 100mm x500mm. The upper platen has also a pair of rollers whose distance is adjustable. It is 200mm centre to centre, for 150mm x 150mm x 700mm size beam and 133 mm for 100 mm x 100 mm x 500 mm size beam. A pressure gauge to indicate load is fixed on the load frame. A small pumping unit is attached to the load frame. The total capacity of the machine is 100 KN and a 150mm dia pressure gauge 0-100 KN x 1 KN is fitted on the machine Since this is a hand operated the lightweight machine, it is useful for field laboratory also.

Compression Testing Machine Electrically operated

The machine embodies a Hydraulic system designed to meet the requirement of Indian Standards Specification 516-1959 for compression tests on concrete Cubes up to 5cm x 5cm x 5cm 7.06cm x 7.06cm x 7.06cm, 10cm x 10cm x 10cm and 15cm x 15cm and also concrete Cylinders up to 10 x 20cm, 15 x 30 cm height.

System Description :

The complete unit comprises of:

Loading Unit:- The hydraulic jack is fixed to the base. The upper platen has got a self-aligning action and is attached to a screw, which passes thru 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 platen of the machine is hardened, ground and polished. Guidelines are marked on the lower platen to keep the specimen coaxial with the hydraulic jack.

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 220/440 Volts 50 cycles electric motor. A 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 thru a push-button starter.

Hose Pipe. A junction box is suitably fixed to connect the motor to the mains thru a push-button starter. The pumping unit is fitted with a 20 cm diam dial hydraulic Pressure Gauge with 100 division i.e. calibrated against N.C.B. Tested proving ring. A max red pointer is provided to facilitate taking readings after the failure of the specimen. The Machine is fitted with a hand wheel control which enables the rate of application of a 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 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 break down of power supply, the motor will not re-start unless the starting switch is operated As fully described above but with One Pressure Gauge, Two Pressure Gauges, and three Pressure Gauges.

Product Details:

Percentage Refuse Density is defined as the ratio of the initial dried bulk density of the sample to the final density (refusal density) expressed as a percentage.
The sample bulk density is determined by weighing in air
and water. It is then heated in a split mould and compacted
to refusal using a vibrating hammer. The final density is
obtained by weighing in air and water .
