Normal Strength Of Concrete Blocks

HOt Products

Which is Stronger Concrete Blocks or Conventional

Apr 22, 2019The Masonry Advisory Council states that the minimum compressive strength for concrete blocks is 1900 pounds per square inch. Although, keep in mind, dense blocks are often stronger than this. The Mechanical Properties of Unreinforced Brick Masonry reports that the average concrete block can handle around 3500 psi.

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.
