Effects of Surface Modification of Rubber Particles on Pavement Concrete Performance

Research Progress on Frost Durability of Rubber Recycled Concrete

“…Some scholars have found that the performance of rubber concrete can be further optimized by modifying rubber. Liu Songan, Liu Yafei et al [38] used different reagents to modify rubber particles, the results show that the use of synthetic resin modification can effectively improve the freezing resistance of rubber concrete, epoxy resin, unsaturated resin modification although it can improve the mechanical properties of the concrete, but make the concrete freezing resistance and resistance to sulfate erosion performance decreased significantly. Su Youwen and Yang Qinsong [39] used different kinds of polymer emulsions to modify rubber concrete, and found that styrenebutadiene emulsion and synthetic resin had a better effect on the improvement of frost resistance of rubber concrete, and the optimal mixing amount was 3%.…”
