摘要：

The abrasion resistance of concrete containing nano-particles for pavement is experimentally studied. Both nano-TiO2 and nano-SiO2 are, respectively, employed to be as the additives. For comparison, the abrasion resistance of plain concrete and the concrete containing polypropylene (PP) fibers is also experimentally studied in this work. The test results indicate that the abrasion resistance of concretes containing nano-particles and PP fibers is significantly improved. However, the indices of abrasion resistance of concrete containing nano-particles are much larger than that of concrete containing PP fibers. The abrasion resistance of concrete containing nano-TiO2 is better than that containing the same amount of nano-SiO2. The enhanced extent of the abrasion resistance of concrete decreases with increasing content of nano-particles. Finally, the relationship between the indices of abrasion resistance and compressive strength of concrete is obtained, which indicates that the abrasion resistance of concrete increases with increasing compressive strength.
