Why we use 150 mm size cube for compressive

2019-12-11  If cube is too small, we won’t get true strength due to large coarse grain present in concrete which create anisotropy in concrete. 150 mm is roughly half foot, so it is good round number to use. But we use other cube sizes for different specific purposes like we test 100 mm cubes for concrete made of 10 mm coarse grain material.
