Aggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone.

Aggregate is a component of composite materials such as concrete and asphalt concrete. It serves as reinforcement (adding strength to the overall composite material), and for forming concrete mortar (by mixing with water, bitumen, Portland cement, lime and gypsum). It is also used as base material under foundations, roads, and railroads.
