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 (ƒ c ) 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 ƒ c 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 ƒ c . But a reduction in the rubber concrete’s ƒ c 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 ƒ c 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 ƒ c of concrete was found to be affected by substituting concrete aggregates with rubber.

INTRODUCTION Presently, sustainability is a significant concern around the world, and cement and concrete technology has an impact on it. The construction sector, especially cement and concrete, is mainly accountable for 7% of total global CO 2 emissions. Concrete competence of sustainable construction is distinguished by the use of industrial wastes to reduce the consumption of natural resources and energy, as well as environmental pollution. Sustainable concrete is more environmentally friendly due to the replacement of materials over nominal concrete. The land is required for concrete construction. Materials for construction activities (aggregates, cement, waters, admixtures, etc.) sourced from quarry sites and borrow pits may result in the wholesale elimination of vegetation and vir- * Address correspondence to this author at the Department of Civil Engineering, Afe Babalola University, Ado-Ekiti, Ekiti State, Nigeria; E-mail: [email protected] gin materials. It can also result in the displacement of populations and the loss of vital ecological resources and biodiversity on a national, regional, or global scale. Based on the foregoing, it became necessary to investigate and review the use of waste materials as concrete coarse aggregates to reduce the risks associated with natural coarse aggregate production and quarrying. The aggregate manufacturing process has numerous significant environmental impacts. The most significant environmental impact of stone, aggregate, and mineral mining is air pollution caused by airborne emissions from both stack and disturbed areas at these mines. Natural aggregate deposit sources are being depleted, posing a threat to the environment and society. The rapid depletion of natural aggregates from source beds causes a variety of issues, including the loss of water-retaining strata, bank slides, exposure of water supply scheme intake wells, and decreasing underground water table levels, all of which cause negative agricultural effects and aquatic life disturbances.
