Properties of Concrete Using Crushed Brick as Aggregate

Brick aggregate can be used to produce high-grade quality concrete. The unit weight is about 125 to 130 lb per ft3 (2000 to 2080 kg/m3). As the properties of brick aggregate concrete lie between those of normal weight and lightweight concrete, it may be classified as medium weight concrete.

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.
