Properties of Bricks

ASTM C73 (ref. 12) covers brick made from sand and lime. Two grades are included: Grade SW—Brick intended for exposures below freezing in the presence of moisture. Minimum compressive strength requirements are 4,500 psi (31 MPa) for an individual unit and 5,500 psi (37.9 MPa) for an average of three units, based on average gross area.

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, i.e. not hollow.

Grades of Concrete

A concrete brick typically weighs more than a clay brick due to its higher density. The higher density of concrete brick is correlated to fewer air pockets and consequently to a lower water absorption rate. Concrete bricks will typically have a higher compressive strength than clay bricks. Insulating Value:

ASTM C780 contains no requirement for minimum compressive strength of field mortar. The mortar strength in the wall will be much higher than the field test because of the reduced water cement ratio due absorption of mix water into the masonry units and a greatly reduced shape factor in the mortar joint versus the mortar test cube.
