The action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone. Crushing, screening, and washing may be used to process aggregates from either sand and gravel deposits or stone quarries. Aggregates may be produced from igneous, sedimentary, or metamorphic.

Jan 01, 2019 Particle size distribution curves of recycled aggregates from building demolition concrete crushed by jaw and impact crushers. The jaw crusher produced 60 of coarse aggregates in weight, whereas the impact crusher produced 49 coarse aggregates. The proportion of particles finer than 0.15 mm is around 7–8 weight for both crushing mechanisms.

Concrete is a mixture of several materials. At the hardened state, this heterogeneous material becomes stone-like mass. The extensive use of concrete in the construction field has made it a material of huge concern for engineers. To participate in the vast uses of concrete an engineer must know its properties.

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.
