Concrete is a mixture of hydraulic cement, aggregates, and water, with or without admixtures, fibers, or other cementi-tious materials. Aggregates are granular materials such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag.

Coarse aggregate is a term used to describe the larger-sized particles that form the bulk of concrete mixes. These particles are typically greater than 4.75 mm (0.187 inches) in diameter. Coarse aggregates are obtained from natural sources, such as quarries, or can be manufactured by crushing rocks or recycling concrete waste.

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/m3 (150-181 lb/ft3).
The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m 3 (75-110 lb/ft 3). Here, the Standard test method for determining the bulk density of aggregates is given in ASTM C 29 (AASHTO T 19).
