Concrete Block |

The concrete commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel. This produces a light gray block with a fine surface texture and a high compressive strength. A typical concrete block weighs 3843 lb ( kg).

CONCRETE MASONRY MANUAL SA Plans

The compressive strength of a unit is based on its gross or overall area. The class of masonry unit required is described by reference to its nominal compressive strength in MPa. The minimum strength of blocks is 3,5 MPa and of bricks 7 MPa. Normally all units with a compressive strength exceeding 10,5 MPa are solid, not hollow.
