Abstract

This investigation was carried out to evaluate the combined effect of crumb rubber (CR) and steel fibers (SFs) on improving the impact resistance of self-consolidating concrete (SCC) mixtures. Seven SCC mixtures were developed with varied percentages of CR (0–15% by volume of sand) and SF’s volume of 0.35%. The performance of the developed mixtures was evaluated by testing the fresh properties, compressive strength, splitting tensile strength (STS), flexural strength (FS), and impact loading (drop weight on cylindrical and beam specimens). The results indicated that inclusion of CR decreased the compressive strength, STS, and FS of the tested mixtures, while the impact resistance obviously increased. Reinforcing CR mixtures with 0.35% SFs could compensate the reduction in the tensile strength resulting from adding rubber and further increase the resistance of mixtures to impact loading, achieving mixtures with promising properties for multiple structural applications.
