اقرأ أكثرDensity 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.

اقرأ أكثرCrushed 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.
