Methods of concrete cube test . So, 100mmx100mmx100mm concrete cubes are used in place of 150mmx150mmx150mm cubes to raise the used stress to crush the concrete cubes. For normal concrete strength, the cube size of 150mmx150mmx150mm is already sufficient for the crushing strength of the machine. Cube Test: Instrument And Material.

The cubes should be covered with a damp cloth and a plastic sheet and stored in dry environment at a temperature range of 20 ± 5 degrees. The concrete cubes are removed from the moulds a minimum 16 hours later to a maximum 72 hours, usually this done after 24 hours. Make sure the cube ID is transferred to the cube before placing into a curing

The testing machine must be accurate, well-calibrated, and having capacity adequate enough to crush the concrete cube. Do not exceed 90% of the capacity of the machine while testing. If the cube does not crush, cut off the machine and use a machine of higher capacity. It is necessary to use a certified and tested proving ring.

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.
