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 parts, lime part, sand and gravel 6 parts, and were tamped from damp mixture. It is probably safe to assume that the minimum crushing strength of wellmade blocks, 1 to 5, is 1,000 pounds per square inch at 1 month and 2,000 pounds at 1 year.

For years, designers have been specifying an f'm equal to 1500 psi with Type S mortar using the unit strength method. 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,, 2000 psi, 2500 psi and 3000 psi with Type S mortar. ...
