Description

This test is used to determine the compressive strength of a concrete cube, which has usually been made from a fresh concrete cast in a standard test mould. The value of compressive strength can then be used to assess whether the batch that the concrete cube represents meets the required compressive strength. Following cube manufacture and curing, which should both be closely controlled, the cube is crushed at a stated constant speed until it can sustain no further increase in load. The strength is then derived by calculation using the maximum load and cube dimensions.

The machine embodies a hydraulic system designed to meet the requirements of Indian standards Specification 516-1959 for compression tests on concrete cubes up to 20 cm X 20 cm X 20 cm. and also concrete cylinders up to 30 cm height. Using special platens and fixture, Brick testing and flexural testing can also be carried out on the same machine.
