“…One is water absorption, rubber particles porous, can absorb free water, reduce slump. The other is the effect of air entraining, rubber particles can increase the content of gas inside concrete, improve liquidity [19][20][21][22][23][24].

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 construction industry, rubber extracted from waste tires can be added to concrete to alleviate environmental problems 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 hardened performance of rubber concrete, especially the durability. Based on the current research results, the workability 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 summarized 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.
