    Apr 01 2018 Concrete elements are designed on the basis of a 28-day cubes crushing strength. A 28-day cubes strength actually represents the characteristic strength of the concrete. It is mandatory to test the concrete cubes or cylinders at the age of 28 days as per almost all building code requirements.

    Procedure for Casting of Cubes and Testing Concrete Cube

    However when the intended concrete strength is 100MPa under the equivalent force about2000kN delivered by the machine the stress under a 150mmx150mmx150mm cube is inadequate to crush the concrete cube. So 100mmx100mmx100mm concrete cubes are used in place of 150mmx150mmx150mm cubes to raise the used stress to crush the concrete cubes.
