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.

Crushed stone. Crushed stone is a type of medium-sized gravel that is formed by mechanically crushing stone. Most commonly, limestone, dolomite, or granite is crushed to form the crushed stone. In certain definitions of the term, crushed stone is not considered gravel since it is a processed rather than naturally-occurring rock fragment.

The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn''t as complex as you may think because water''s density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
