Abstract

The use of superplasticisers to enhance concrete properties is standard practice in concrete manufacture. The present study aimed to assess the compatibility of these admixtures with recycled construction and demolition waste (with or without lightweight materials) aggregate on some the physical and mechanical properties of the resulting concrete. The paper reports on the 0 and 50% replacement of natural coarse aggregate in a conventional concrete with mixed recycled coarse aggregate.

The experimental technique used was based on the study of water absorption as well as the compressive and splitting tensile strength of such recycled concretes.

The superplasticiser was found to be compatible with this type of recycled aggregate, for no decline in concrete performance was observed.
