Importance of Gravel and Sand for Concrete | Hunker

Concrete is made up of cement and water plus an aggregate composed of sand and gravel. The sand and gravel do more than act as filler, though. The size and amount of gravel added to a bag of concrete also determines the product's volume, strength, and durability.

Aggregates

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.
