If we design the mix for M150 grade means permissible will be 150kg/cm^2 only. Sometimes during testing due to some variations strength decreases for ex.130 or 135kg/cm^2 or 200kg/cm^2 even if we designed for M150 grade concrete.

What is Compressive Strength? - Matmatch
Compressive strength refers to the ability of a certain material or structural element to withstand loads that reduce the size of that material, or structural element, when applied. A force is applied to the top and bottom of a test sample, until the sample fractures or is deformed.. Materials such as concrete and rock are often evaluated using a compressive strength test and in these cases
