Technical Guidance Concrete Block Strength

If HS is greater than 2.7m, the compressive strength of bricks or blocks used in the wall should be at least Condition B, or as indicated by the key, whichever is the greater. If the external wall is solid construction, the masonry units should have a compressive strength of at least that shown for the internal leaf of a cavity wall in the same position.

What is the compressive strength of solid concrete block ...

In any case, hollow blocks, solid blocks and concrete bricks are usually made of the same mix design. Blocks are typically around 10 to (exceptionally) 20MPa. (Note that our way of expressing strength may not be the same in your country) Concrete bricks may have similar compressive strengths. Fired clay bricks may be stronger. Or not.

Compressive Strength Concrete Blocks Masonry Units

Note down the load at which masonry unit fails and the maximum load divided by gross sectional area of unit will give the compressive strength of block. Similarly, test the remaining 7 blocks and the average of 8 blocks strength is the final compressive strength of concrete masonry unit.

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.

The range of strength for sandcrete blocks specified by N.I.S 74:1976 is between1.8N/mm2 to 2.5N/mm2 as the minimum strength. The blocks can cope with thermal and moisture conditions, and the problem of algae growth on the face of block work during construction is unlikely to affect the strength of the block (Edward, 1985).
