Is the compressive strength of mortar important Masonry
For ASTM C90 concrete block, the assembly compressive strength only increases 250 psi when the mortar is changed from Type N to Type S from an f m of 1750 psi to 2000 psi for CMU units with 2000 psi compressive strength. The compressive strength of the masonry units is the largest factor, by far, in masonry assembly compressive strength.

Specified Compressive Strength of Concrete Masonry fm
According to the Code this would require a block compressive strength of 1900 psi. Recently on projects, some designers are now specifying a higher fm, 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.
