In this study, Powder X-ray diffraction (XRD)/Rietveld analysis, which has been utilized in recent years as a technique for quantifying the crystal mineral phase of cement and cement paste, was applied to quantify the reaction rate of cement minerals and the proportions of hydration products. Its accuracy and availability was verified by comparing with the following properties, reaction rate of minerals by internal standard methods of XRD quantitative analysis, rate of heat liberation of cement by conduction calorimeter and amount of combined water of cement paste. Experimental factors were three types of cements, three levels of W/C, three levels of mixing/curing temperatures. The results showed that XRD/Rietveld analysis can quantify the hydration rates and products of cement paste with high accuracy.
