In the case of 9 inches block the compressive strength is 2.59 N/mm2 and 3.94 N/mm2 for ages 7 days and 28 days respectively. This shows that there is a variation in compressive strength between the two blocks. To this end, it can be deduced that the strength of 9 inches block is more and higher than that of the 6 inches block.
