There are mainly two types of aggregates used by civil engineering construction work to prepare concret. Concrete are used for different purpose like foundation, pavement etc. About 40 to 80 percent of concrete is made up of aggregate. So, aggregates used in concrete must be free from dust, clay, organic materails like vegetable, leaves etc.

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 kg/m 3 (150-181 lb/ft 3).
