Abstract 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… More >

Abstract A composite rubber concrete (CRC) was designed by combining waste tire rubber particles with particle sizes of 3~5 mm, 1~3 mm and 20 mesh. Taking the rubber content of different particle sizes as the influencing factors, the range and variance analysis of the mechanical and impermeability properties of CRC was carried out by orthogonal test. Through analysis, it is concluded that the optimal proportion of 3~5 mm, 1~3 mm, and 20 mesh particle size composite rubber is 1:2.5:5. 5 kinds of CRC and 3 kinds of ordinary single-mixed rubber concrete (RC) with a total content of 10%~20% were designed under… More >
