Is the compressive strength of mortar important?

ANSWER: Compressive Strength. In load-bearing masonry, mortar compressive strength may have some importance, but mortar only contributes a small amount to masonry assembly compressive strength (f’ m).). 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
