New study on use of RCA in structural concrete

摘要

A recent study funded by WRAP (Waste & Resources Action Programme) analyses whether the strength and performance of structural concrete made using recycled concrete aggregates (RCA) can be predicted by applying the same design formulae used for concrete containing primary aggregates. The aim of the project was to identify whether the use of RCA affects the applicability of engineering property relations for concrete-based compressive strength, given in structural design Eurocode 1992 (EC2).The study also assessed whether the ultimate strength of concrete structural members containing RCA can be predicted through compressive strength testing, also as defined in EC2.
