Standards Specification

516-1959 for compression tests on concrete Cubes upto 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 upto 10 x 20cm 15 x 30 cm height

Loading Unit :- The hydraulic jack of 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 jackram 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 hardended ground and polished. Guidelines are marked on the lower platen to keep the specimen coaxial with the hydraulic jack.

Pumping Unit :- The motorised 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. The pumping unit is a separate unit connected to the jack by means of a Rubber Hose Pipe. A junction box is suitable fixed to connect the motor to the mains thru a push button starter.Hose Pipe. A junction box is suitable 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.
