    However if the designed concrete strength is 100MPa under the same force (about 2 000kN) supplied by the machine the stress under a 150mmx150mmx150mm cube is not sufficient to crush the concrete cube. Therefore 100mmx100mmx100mm concrete cubes are used instead to increase the applied stress to crush the concrete cubes.
