Use of AFM technique to study the nano– silica effects in concrete mixture


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.
