Traditional cement based material has low strength. By adding 2-5 silica nanoparticles instead of ordinary concrete materials the performance of concrete will enhance.With special nano treatment the surface area of nano silica can be larger easier to cement and hydration in the formation of chemical bonds to CSH gel.

Silicon dioxideWikipedia

Silicon dioxide also known as silica is an oxide of silicon with the chemical formula Si O 2 most commonly found in nature as quartz and in various living organisms. In many parts of the world silica is the major constituent of sand.Silica is one of the most complex and most abundant families of materials existing as a compound of several minerals and as synthetic product.
