Whether compressive strength of 100mm cube or 150mm

2015-9-16  Compressive strength of 100mm cube is greater than the compressive strength of 150mm. The reason is that.. 1) If we mould concrete into cube having a small demension like 100 X 100 X 100 mm^3 the bonding is very good than the 150 mm^3 cube. we know that as the size of the cube or beam increasing the void spaces in it also increases.
