uses of recycled aggregates in construction

Can I Use Crushed Concrete for Paver Base?,  · Due to the large porosity of recycled aggregates, their water absorption rate is large, the resistance to deformation is poor, and the drying shrinkage of the recycled concrete is greatly increased. So, crushed concrete is enough good for drainage of a paver base and can be used.Aggregate,  · Construction aggregate, materials used in construction, including sand, gravel, crushed stone, slag, or recycled crushed concrete Other uses in science Aggregate (geology), a mass of crystals, rock particles, or soil particles Aggregate (rocket family)Technological Advancements in Construction,  · In an initiative by the Building and Construction Authority, the Samwoh Corporation, and Nanyang Technological University, a method to recycle construction and demolition waste was developed to form Recycled Concrete Aggregates (RCA).
