Density of Construction Materials in kg/m3 and lb/ft3

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.

The most common methods to conduct in-place field density testing for soil particles are by the Sand Cone Method (ASTM D-1556) and by the Nuclear Method (ASTM D- 2922 for shallow depth and ASTM D-5195 for nuclear probe depths below the fill surface). These field density test methods for earthfill soil particles become less effective or accurate
