Why we use 150 mm size cube for compressive strength ...

150 mm is the ideal size for cube making. It is big enough to take coarse grains of 20 mm size and small enough to be handled easily. If the cube is too big, handling will be difficult. Also, the load required to test will be much higher which is another problem.

Difference Between M25 and M30 Concrete | What Is M25 ...

Method 3: Take a sample of each in a container/cistern (of equal volume) and fill them The CSA ratio of the M25 is 1: 1: 2, while that of the M30 is mix design (but is generally greater than M25). As the weight of the aggregate is dominating the mixture, the weight of the M30 sample will be greater. Thus, we can differentiate between samples.
