Abstract The influence of Nano particles on mechanical properties and durability of concrete has been investigated. For this purpose, constant content of Nano-ZrO2 (NZ), Nano-Fe3O4 (NF), Nano TiO2 (NT) and Nano-Al2O3 (NA) have been added to concrete mixtures. Mechanical properties have been investigated through the compressive and indirect tensile strength and durability has been investigated through chloride penetration test and concrete permeability. Results of this study showed that Nano particles can be very effective in improvement of both mechanical properties and durability of concrete. Results of this study seem to indicate that the Nano-Al2O3 is most effective nano-particle of examined nano materials in improvement of mechanical properties of high performance concrete.

State-of-the-art report on use of nano-materials in concrete (2014, result): “A similar finding was obtained from other research: according to Shekari and Razzaghi (2011), a constant amount (1.5 wt% of cement) of nano-ZrO2, nanoFe2O4, nano-TiO2 and nano-Al2O3 showed a reduction of chloride penetration in the range of 20–80%.”
Use of nano-silica in cement based materials—A review (2015, background): “Few studies till date are reported with nanoparticles such as nano-silica (nano-SiO2) and nano-titanium oxide (nano-TiO2), nano-iron (nano-Fe2O3), nano-alumina (nano-Al2O3) (Li, 2004; Shekari & Razzaghi, 2011).”
