Abstract

Recycled concrete fines (RCF) are fine aggregates and particles from the demolition waste of old concrete. Unlike recycled coarse aggregates, RCF is seldom used to replace sands in concrete due to its high surface area and attached old mortar on the surface of RCF. This paper reports on a study of the replacement of sand by RCF in the production of Engineered Cementitious Composites (ECC). ECC is a high performance fiber-reinforced cementitious composite which exhibits tensile strain-hardening behavior with extreme tensile ductility of 3-5%. Itwas found that ECC specimens with RCF yielded a higher tensile strengthwhile maintaining high tensile ductility.And ECC incorporates high RCF content can still achieve tensile strain-hardening behavior. This study confirms the potential of incorporating RCF into ECC.
