DSC was used in order to evaluate the reactivity of cement raw meal. Two groups of samples were studied: five industrial raw meals for ordinary Portland cement production, with similar compositions, but differences in granulometry; and five industrial raw meals for white Portland cement production, with similar granulometric features, but different compositions. The burnability indices of the samples were correlated with certain data obtained from the DSC curves. It is concluded that the DSC curve data, and especially the temperature and enthalpy effect of belite formation, are strongly correlated with the burnability of the cement raw meal. The temperature of belite formation is affected by chemical and mineralogical factors, while the enthalpy effect is additionally affected by the fineness of the raw meal. (EN)
