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.

Durability of recycled aggregate concrete with

Each of the mineral admixture is used independently in the recycled aggregate concrete. The different%age replacement of natural coarse aggregates by recycled aggregates considered are 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100%. The compressive strength of concrete subjected to 45 cycles of alternate wetting and drying is determined.

equipments used for recycled aggregate concrete
