Study of phase composition of Ordinary Portland Cement Concrete using X-Ray Diffraction [ ]

An experimental study is performed on powder ordinary Portland cement concrete samples using X- ray diffraction (XRD) which reveals a promising approach for phase composition of concrete structures. Conventional X-ray diffractometer was used for XRD analysis of concrete samples. The potential presence of cement content and silica in hardened ordinary Portland cement concrete can be determined by X-ray diffrac-tion analysis. This approach may replace the traditional chemical analysis of hardened concrete which is tedious and time consuming .An attempt has been made to quantify the phases present in ordinary portland ce-ment concrete . The results of phase quantification obtained from XRD analysis has shown good agreement with the experimental values.
