Density is also called as unit weight of substance. It is represented by symbol called row ( p). Density represents the degree of compactness of material. If the material is of more density, it is more compacted material. Density is defined as the ratio of mass to volume. p = m/v Units = kg/m 3 or lb/ft 3 Conversion: 1 kg/m 3 = 0.624 lb/ft 3.

Aggregate Density: Most of the aggregates possess a relative density within 2.4-2.9 with a similar particle density of about 2400-2900 Kg/m 3 (150-181 lb/ft 3). Density of Sand and Aggregate: Density of coarse sand is ranging between 1450-2082 kg/m 3 depending on different conditions like wet, dry, loose, dry-packed, and wet packed.
