Procedure for Casting of Cubes and Testing | Concrete Cube ...

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.
