Workability and Durability of Concrete Incorporating Waste Tire Rubber: A Review

Environmental problems caused by waste tires are becoming increasingly prominent. There is an urgent need to find a green way to dispose of waste tires, and scholars have made considerable efforts in this regard. In the con-struction industry, rubber extracted from waste tires can be added to concrete to alleviate environmental pro-blems to a certain extent. As a new building material, rubber concrete has superior properties compared to ordinary concrete and has been widely used in many fields. Numerous studies have been conducted worldwide to investigate the effect of waste tire rubber on the performance of concrete. It has been reported that the addition of waste tire rubber has a significant influence on the performance of concrete. Workability influences the har-dened performance of rubber concrete, especially the durability. Based on the current research results, the work-ability and durability of concrete manufactured with waste tire rubber, including water absorption and permeability, carbonation resistance, chloride ion permeability resistance, and freeze-thaw resistance, are sum-marized in this paper. It is concluded that the addition of waste tires has a negative effect on the workability of concrete. In terms of durability, concrete exhibits better chloride ion penetration resistance and frost resistance, with a higher water absorption rate, and lower anti-permeability and carbonation resistance owing to the addition of waste tire rubber.
