abstract. for resource reutilization, scrap tyres have long been investigated as an additive to concrete to form ‘rubcrete’ for various applications and have shown promising results. however, the addition of rubber particles leads to the degradation of physical properties, particularly, the compressive strength of the concrete.,effect of using ground waste tire rubber as fine aggregate,concrete. the cement content for concrete mixes is 300, 400, and 500 kg/m3. the total fine aggregate (tfa) in all mixes is sand, which is partially replaced by gwtr particles. the percentages by volume of gwtr/tfa are 5%, 10%, 15% and 20%. the physical and mechanical properties of rubberized concrete are compared with those of ordinary concrete mixes.
