Impact Property of Concrete Containing Nano-Particles for Pavement
Impact property of concrete containing nano-particles (TiO2 or SiO2) for pavement is experimentally studied and compared with that of plain concrete, concrete containing PP fibers and concrete containing both nano-TiO2 and PP fibers. The test results indicate that the impact property of concrete is enhanced when the amount of nano-particles is smaller. However, the impact property of concrete is reduced when the amount of nano-particles is larger. The impact property of concrete containing PP fibers is improved, and the impact property of concrete containing both nano-TiO2 and PP fibers is decreased. There is a significant linear relationship between impact property and flexural strength of pavement concrete.
