Effect of nanoparticles on frost durability of concrete

The influence of nano-TiO2, nano-Al2O3, nano-Fe2O3 and nano-ZnO2 on durability and mechanical properties of concrete was experimentally investigated. For this purpose, compressive strength tests were conducted in order to investigate the effects of nano particles on mechanical properties of concrete. Moreover water absorption and freeze and thaw tests were conducted to explore the effect of nano particles on durability of concrete. Results of this study showed that all the examined nano particles can improve durability and mechanical properties of concrete. The contribution of nano-TiO2 on improvement of mechanical properties and durability of concrete was more than the other nano particles.
