Abstract

— This present study aims to investigate experimentally the use of recycled aggregates in high strength concrete using metakaolin as a mineral admixture. In this study, the natural fine aggregates were replaced with recycled fine aggregates (RFA) at 10%, 20%, 30%, 40% and 50% while keeping a constant replacement of recycled coarse aggregate (RCA) at 30%. The compressive as well as durability properties like acid resistance and sulphate attack have also been investigated. It was observed that the replacement of sand with RFA up to 10% gave higher strength than the normal control mix (NCM) in terms of compressive strength at later ages. The specimens exposed to sulphate attack also showed a similar trend in terms of compressive strength.
