Abstract: This research was conducted to investigate the effect of using crumb rubber (CR) on improving the impact resistance of self-consolidating concrete mixtures. The variables were percentage of CR (0–40% by volume of sand), binder content (500–550 kg/m3), and use of metakaolin. Tests included fresh properties, compressive strength, and impact loading (drop weight on cylindrical specimens). The results indicated that the impact energy required to initiate the first visible crack and/or ultimate failure crack of the tested specimens increased up to 30% CR replacement. A further increase in the percentage of CR appeared to have a negative influence on the impact resistance of rubber-concrete composite. The results also showed the effect of increasing binder content and use of metakaolin on improving the stability of mixtures and exhibiting higher impact resistance.
