When it is expressed in the basic SI Unit of mass (kg/m 3 ), it is usually referred to as density, but when expressed in terms of weight (kN/m 3 ), it is usually referred to as unit weight.

Cross-sectional area is the basis for expressing compressive strength of concrete masonry units. .

p = m/v Units = kg/m 3 or lb/ft 3 Conversion: 1 kg/m 3 = 0. as the material is fabricated into masonry units or bricks, the density of the basic material is unchanged, but the unit weight of the finished product can be lower because of.

High-density blocks are generally.

3) defines three density classes for concrete masonry units: Lightweight – units having an average density less than 105 lb/ft 3 (1,680 kg/m 3).
