Abstract: The mineralogical composition of high alumina cement (HAC) determines its ultimate properties once it has been mixed with water. The mineralogy of HAC cannot be given from the chemical composition because the thermodynamic equilibrium usually is not reached during the production process. The Rietveld method permits relatively quick quantitative phase analysis by fitting the calculated X-ray diffraction (XRD) profile with the observed one. Synthetic mixtures of pure phases were analyzed with this method in order to obtain a set of "empirical corrections" to be applied to samples of HAC clinker without previous chemical treatment. Chemical composition estimated from the weight percent of phases was in good agreement with composition obtained by X-ray fluorescence (XRF).
