Rate Of Crushing Concrete Cubes. After that crushing is done in the usual way. the cube can be tested after 3, 7, 14 and 28 days. cube is placed in compression testing machine and axial load is applied at the rate of 140 kg/ cm2. in actual concrete is required sufficient time to gain strength. usually 28 days strength is considered as the full strength of concrete..

The compressive strength of the concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.

The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved at 28
