    The X-ray diffraction analysis of some materials did not indicate significant differences in terms of proportions of the phases. Therefore, the cements were analyzed semi-quantitatively, using the Rietveld method to help interpret the results. This analysis involved only the CA 2-cements. The results of this analysis are shown in Table 2.
