According to the Code this would require a block compressive strength of 1900 psi. Recently on projects, some designers are now specifying a higher f’m, i.e., 2000 psi, 2500 psi and 3000 psi with Type S mortar. According to the Code this would require a block compressive strength of 2800 psi, 3750 psi and 4800 psi, respectively.

In the case of 9 inches block the compressive strength is 2.59 N/mm 2 and 3.94 N/mm 2 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.
