In this work we evaluate the role of a natural mineralizer-oxide like cassiterite (SnO₂) on the cement properties. In particular, we study the effect of different quantities of SnO₂ with 0.5, 1.0, 1.5 and 2.0 wt% on burnability of industrial raw mix by free lime evaluation. We obtain four datasets, with successive increase of temperature at 1250℃, 1350℃, 1400℃ and 1450℃. We study the produced cassiterite-added clinker with X-ray diffraction (XRD), thermal analysis (DTA) and scanning electron microscopy (SEM). Though, we characterize the new phases formed and whether, adding excess SnO₂ is promote forms of C₃S, C₂S influencing the final quality of cement.
