The compressive strength of concrete is the most common performance measure used by the engineer in designing buildings and other structur The compressive strength is measured by breaking cylin drical concrete specimens in a compression testing machine The compressive strength is calculated from the failure load divided by the cross sectional area resisting the load and In concrete compression test normally 150mm x150mm Basically the force supplied by a concrete compression machine is a definite value For normal concrete strength application say below 50MPa the stress produced by a 150mmx150mmx150mm cube is sufficient for the machine to crush the concrete
