The relative density specific gravity of an aggregate is the ratio of its mass to the mass of an equal volume of water. Relative Density Mass of the Aggregate Mass of equal volume of water. Key Features Most aggregates have a relative density between 2.4-2.9 with a corresponding particle mass density of 2400-2900 kgm 3 150-181 lbft 3.
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 mv Units kgm 3 or lbft 3 Conversion 1 kgm 3 0.624 lbft 3.

Rock size is primarily dependent on flow velocity V, rock shape round or angular, and rock density s r. The establishment of vegetation over the rocks can improve the aesthetics, but can significantly change the hydraulic roughness and therefore the flow capacity. 2. Sizing of rock used in lining of drainage channels
