### Density of Aggregate

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 24-29 with a corresponding particle (mass) density of 2400-2900 kg/m 3 (150-181 lb/ft 3)...
