摘要
The abrasion resistance and chloride permeability of concrete containing nano-SiO2 in the amount of 3% by the weight of binder and nano-TiO2 in the amount of 5% by the weight of binder were experimentally studied and compared with that of plain concrete with the same water-binder ratio. The results showed that the abrasion resistance and resistance to chloride penetration of concrete containing 3% nano-SiO2 and 5% nano-TiO2 were higher than that of plain concrete and the SEM study of concrete microstructure also confirmed the results. The origin of nanoparticles improving abrasion resistance and resistance to chloride penetration of concrete was also presented from the microstructure standpoint.
