Enhancement Treatment of Recycled Concrete Aggregate

Jul 22, 2021  Aggregate is an essential component in concrete, occupying 60–70% of the concrete by volume. Nevertheless, the application of natural aggregate (NA) is restricted due to the finite resources and long regeneration period. Recycled concrete aggregate (RCA), as common CD waste, has received widespread attention for its usage to replace NA.

End of life recycling

A specific subset of recycled aggregates is recycled concrete aggregates (RCA) where the masonry content is limited to not more than five per cent. The performance characteristics of RCA are better than RA and consequently there are fewer restrictions on the use of RCA in concrete. Provision for the use of RCA in concrete is given in BS 8500-2.
