Abstract. Regarding the performance of Nano-silica in cement based materials such as cement paste, mortar and concrete there are different outcomes revealed by researchers that fluctuates around significant increase or decrease in resistance of due materials. In the present research the impact of different kinds of Nano-silica whether powder or colloids form and special plane with 80 to 500 m2/ gr on characteristics of new and hardened mortar has been investigated. The results indicated that Nano-silica contributes to dramatic decrease in performanceality. As such, to compensate the loss one needs to use super plasticizer. Using Nano-silica increases pressure resistance regarding control mortar and in some cases the level of pressure is more than mortar containing silica fume. Also the majority of increase in Nano-silica resistance takes place during seven days. The size of Nano-silica particles in this research was evaluated by Transmission Electron Microscopy (TEM).

Keywords: nano-silica, size of particles, cement, TEM.
