Recycled Concrete Aggregate an overview ScienceDirect

Recycled concrete aggregate (RCA) is the designation used in BS 8500-2 for recycled aggregate principally comprising crushed concrete. Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concrete.

Recycled Concrete as Aggregate for Structural Concrete

Recycled concrete aggregate was produced by crushing of ―old‖ concrete cubes used for compressive strength testing and one precast reinforced concrete column, which had inappropriate dimensions (Figure 1). The strength class of old concrete cubes was C30/37 and the corresponding value of compressive strength for precast column was C40/50

Use of recycled concrete aggregate in concrete: a review

The use of recycled concrete aggregate (RCA) in concrete as partial and full replacements of natural coarse aggregate is growing interest in the construction industry, as it reduces the demand for virgin aggregate. In addition, the use of RCA leads to a possible solution to the environmental problem caused by concrete waste and reduces the

Said Kenai, in Waste and Supplementary Cementitious Materials in Concrete, 2018. Abstract. Construction industry generates huge amounts of debris that needs to be recycled and reused as recycled aggregates (RAs) for partial or total substitution of natural aggregates. Recycling reduces waste and reduces energy consumption and hence contributes to a more sustainable construction
