Abstract: The polymorphism of alite (C3S) has been subjected to examination through various factors, such as the burning process and cooling. This study is centered on investigating the impact of grinding on alite polymorphism. To determine the chemical composition, X-ray fluorescence (XRF) analysis was employed. The mineralogical characterization was conducted utilizing X-ray powder diffraction (XRD), complemented by the Rietveld method. Morphological assessments of the ground clinker were carried out using scanning electron microscopy (SEM) in conjunction with EDS microanalysis. XRD analysis, performed on both gray and white cement as well as clinker, has revealed that mechanical treatment (grinding), aside from reducing particle size, actively induces the transformation of alite polymorphism from monoclinic M1 to monoclinic M3.
