Study results indicated that cement mortar mixed with Nano size silica particles, 12, 20, 40 nm. With the formation of both the early and the late fast compared with cement mortar and cement mortar, mixed silica fum. In the resistance to abrasion and water permeation rate can be seen that the cement mortar mixed with Nano silica has a value weight loss from abrasion and water permeation rate less than cement mortar, cement mortar and silica mix fum. Show that the cement mortar mixed with Nano silica is the price of high density and nano silica will accelerate the occurrence of biological response output as Paul Palazzo courtyard. calcium silicate tahaiderot (CSH), which improves the capacity, cement mortar and reduce the gap in the cement with a small particle phle in nano-level so it can be inserted into the gap to make cement mortar is the same texture.
