    Recycled Concrete Aggregate - an overview | .

    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.

    Concrete recycling - Wikipedia

    Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete.Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called ...
