BEHAVIOUR OF CONCRETE INCORPORATING TIREDERIVED CRUMB RUBBER AGGREGATE

An experimental study on the performance of concrete containing waste-tires based fine aggregate is presented in this paper. This study examines the effect of replacing the natural fine aggregate (NFA) with recycled fine aggregate (RFA) on the workability and mechanical properties of concrete. The mechanical properties include: compressive strengthand tensile strength. Various RFA replacement ratios were used including (10%, 20%and 30%). Four mixes were examined: three with different RFA replacement ratios and one mix with NFA for comparison purpose. The results show that RFA reduces both the workability and the mechanical properties of concrete.
