Currently, the cement industry uses the coprocessing of industries residues as raw materials or alternative fuel for attending economics and the sustainability aspects. This procedure can introduce a variety of minor elements that can affect the clinkerization reactions by producing morphological changes of the clinker crystals and changing the surface tension and viscosity. Thus, mineralogic and
microstrutural characterizations are necessary to understand the clinker reactivity and its effect on the Portland cement properties. Nonetheless, the number of clinquer kiln control variables is enormous, and it is proposed to use the Principal Component Analysis (PCA) to choose the most important ones. The X-ray diffraction characterization of the clinker showed that the four major constituents are consistent with the theorical values (Bogue potentials). The C3S phase was monoclinic, which is usual for industrial clinkers, and the C3A phase was usually cubic. These results suggest that the formation of a high reactivity clinker. The physico-mechanical characterizations setting time and compressive strength of the Portland cement were conducted according to NBR 16607 and NBR 7215 ABNT norms. The Portland Cement results agreed with the NBR 16697 ABNT norm.
