This study examines the use of rubber particle (RP) recycled from waste vehicle tires, which is one of today's most serious environmental problems in concrete. For this purpose, studies on rubber aggregate concrete (RAC) were compiled and analyzed. The physical, mechanical and durability properties of RAC were investigated. When the results were analyzed, the addition of rubber decreased the compressive and flexural strength, and the modulus of elasticity. The porosity percentage, water absorption, sorptivity and water permeability of RAC generally increased with increasing rubber percentage and rubber size. The addition of rubber aggregate to the concrete increased the toughness of the concrete up to 3 times because of the energy absorbing property of the rubber particles (RPs). Besides, the addition of rubber had positive effects on the properties of concrete such as abrasion resistance and freeze-thaw resistance. The drying shrinkage of RAC varies depending on the percentage, size and stiffness of RPs. The findings reveal that less than 10% of RPs should be used in concrete for structural applications where strength is important.
