COMPRESSION TESTING MACHINE - ELECTRICALLY CUM HAND OPERATED
The concrete is a man-made material, essential mixed at site. The properties of concrete depend on the properties of its ingredients and their proportion, and it is likely to vary from mix to mix. Tests must be conducted, therefore, to ensure that the concrete used is in accordance with design specifications. It is a frequent test of compressive strength, in which concrete samples are tested to failure.
Compression Testing Machine Electrically Cum Hand Operated. The machine embodies an Hydraulic system designed to meet the requirement of Indian 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 x 15cm and also concrete cylinders upto 10 x 20cm, 15 x 30cm 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 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 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 through a push button starter.
Hose Pipe: A junction box is suitable 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 with 100 division i.e. calibrated against N.C.B. Tested proving ring. A max red pointer is provided to facilitate taking readings after failure of the specimen. 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.
