to determine the crushing strength of concrete block

Properties of Concrete Blocks — Strength

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 ...
