Properties of Concrete Blocks — Strength

It is probably safe to assume that the minimum crushing strength of well-made blocks, 1 to 5, is 1,000 pounds per square inch at 1 month and 2,000 pounds at 1 year. A block 12 inches wide and 24 inches long has a total surface of 288 square inches, or, deducting ⅓ for openings, a net area of 192 inches. Such a block, 9 inches high, weighs 130 ...

What is a Compressive Strength?

 · Compressive strength is a limit state of compressive stress that leads to failure in a material in the manner of ductile failure (infinite theoretical yield) or brittle failure (rupture as the result of crack propagation, or sliding along a weak plane). Compressive strength is measured on materials, components and structures.
