Abstract

Concrete with waste steel fibers and crumb rubber (WSFCR) was primarily created using components that are extracted from the scrap tires recycling process. Crumb rubber particles of size (1- 4) mm and relative density 1.0 gm/cm3 were included as a partial replacement (10% by volume) of natural sand. Recycled or waste steel fibers were used in four percentages from the total mass of the concrete (0.5%, 1.0%, 1.5%, and 2.0%). The efficiency of WSFCR has primarily been studied to evaluate its performance against impact loads, compared to the performance of traditional concrete (CR 0), rubber concrete (CR 10%), and rubber concrete reinforced with industrial steel fibers (ISFCR). Also, the influence of recycled steel fibers on the different strengths of the rubberized concrete was presented. A total number of eleven slabs (1000×1000×100 mm) were subjected to 10.738 Kg cylindrical steel weight falling from a 1.5 m distance concerning the number of blows at the first crack formation and complete failure. Both WSFCR and ISFCR showed outstanding performance under impact loads compared to CR0 and CR 10% control mixtures. Although ISFCR resulted in a higher impact energy resistance than WSFCR, which showed convergent results and a similar crack pattern; therefore, it is a strong candidate as a low-cost alternative to industrial steel fibers.
