Jun 30, 2011 • Crushing old concrete to produce aggregate takes less energy than mining virgin aggregate. • Using old concrete helps to conserve virgin aggregate supplies, which are slowly being depleted near larger cities. Historical perspective. When landfills located near populated areas started refusing broken concrete in the 1970s, the construction industry started crushing it to make aggregate.

Aggregates For Concrete

Aggregates For Concrete

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 rocks, but geological type does not by itself make an aggregate.
