Specified Compressive Strength of Concrete Masonry, f'm ...

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.

Verifying Compressive Strength of Masonry - cement

These specimens are built at the job site. Methods for this are outlined in ASTM C1314, Standard Test Method for Compressive Strength of Masonry Prisms, which entails constructing the prisms, including grouting if applicable, and bag curing them. Masonry prisms for compressive strength testing are constructed and then cured in plastic bags.
