Compressive Strength of Chipped Rubber Aggregate Concrete: A Review

Abstract

Concrete is a widely used material for construction therefore, it is necessary to identify materials that are economical, environmentally friendly, easily available, and prevention of environmental damage while sourcing the materials, hence the aim of this study. The current study’s objective is to have a comprehensive study on the previous research identifying the effects of chipped rubber as concrete coarse aggregate and the compressive strength (fc) of the concrete and to identify areas of relevance for better sustainability to reduce the rate of waste rubber and degradation of the environment. To achieve the objectives of this study, a review of previous research works was conducted and analyzed. A comprehensive study on the fc of chipped rubber coarse aggregate concrete (RCAC) was studied by reviewing previous research. The addition of chipped rubber in concrete to a specific ratio can enhance or reduce the concrete fc. But a reduction in the rubber concrete’s fc can be seen when the rubber content ratio exceeded 20%. When the chipped tyre rubber is treated with coupling agents, an increase in the concrete fc can be seen. The use of chipped rubber in concrete production reduces environmental degradation and proves as a step toward the sustainable development goal (SDG). Chipped RCAC mixtures are weaker than regular concrete mixtures. RCAC on the other hand is more ductile and has a better energy dissipation pattern. The fc of concrete was found to be affected by substituting concrete aggregates with rubber.
