Mechanical and Durability Properties of Self-Compacted Concrete Incorporating Waste Crumb Rubber as Sand Replacement: A Review

The lack of disposal facilities for waste tires from various vehicles is a major environmental and economic problem. Crumb rubber (CR) generated can be used to partially replace fine natural aggregates in self-compacted concrete (SCC), lowering sand usage protecting raw material resources. main objective this study summarize the influence CR as partial replacement on behavior SCC. For aim, 42 papers were selected out 89 that relevant study. mechanical properties, i.e., compressive strength, flexural splitting tensile modulus elasticity, bond well ultrasonic pulse velocity (UPV), all reduced by insertion into SCC mixtures. With addition CR, fracture energy decreases, but ductility terms characteristic length enhanced. Meanwhile, replacing with also reduce durability performance SCC, such sorptivity, free-drying shrinkage, rapid chloride permeability, depth penetration, except electrical resistivity, carbonation, impact resistance, which exhibit positive tendency. Based results reviewed articles, predicted reductions strength incorporating recommended. Moreover, studies employed develop empirical models demonstrate relations between properties.
