Nano structural properties of concrete can be studied with considering the variations of the nano silica/Si ratio, the silicate structure, and the contents of Si-OH in the mixture using X- Powder method, AFM (Atomic Force Microscopy) and X- Ray Diffraction (XRD) techniques. We have thus synthesized the nano silica particles by employing sol- gel method. The obtained results are led to a new aspect of the silicate - hydrate, which helps to establish quantitative relations between the nano structure and bulk properties.
