Unit strength relies on individual cmu and masonry grout strengths, and the type of mortar. For example, specifying a high-stress unit at 3250 net psi, an f' m of 2500 net psi would be allowed without substantiation by prism test. Note: CBC Section 2105A.2.1. does not allow the unit strength method for design strengths over 2000 net psi....

Two blocks 6X8X9 inches, 22 months old, showed crushing strength of 2,530 and 2,610 pounds per square inch. These blocks were made of cement 1.25 parts, lime 0.5 part, sand and gravel 6 parts, and were tamped from damp mixture. It is probably safe to assume that the minimum crushing strength of well-made blocks, 1 to 5, is 1,000 pounds per ......
