Study of Using of Recycled Brick Waste (RBW) to produce Environmental Friendly Concrete: A Review


Several million tons of solid waste are produced each year due to construction and demolition activities worldwide, and brick waste is one of the widest wastes. Recently, a growing number of studies have been conducted on using recycling brick waste (RBW) to produce environmentally friendly concrete. The use of brick waste (BW) as potential partial cement or aggregate replacement materials is summarized in this review, where the performance is discussed in the form of the mechanical strength and properties related to the durability of concrete. It was found that, because of the pozzolanic activity of clay brick powder, it can be utilized as a cement substitute in replacement levels up to 10%. Whereas for natural coarse aggregate, recycled aggregate can be used instead of it, but at a limited replacement level. Concrete manufacturing from recycled aggregate can give adequate strength and can be suitable for producing medium or low strength concrete. On the other side, the utilization of fine recycled brick waste as aggregate in concrete manufacturing provides development of the properties of concrete. It develops the durability of concrete in some cases when used with replacement level up to 10% by the weight of fine aggregate.
