The cement industry has been identified as one of the main contributors to climate change due greenhouse gas emissions, mainly CO2. Therefore, meet CO2 reduction targets, producers are working on different strategies minimizing its emission, which is alternative clinkers. This study assessed impact variations raw mix design, concerning type and proportions materials, formation calcium sulphoaluminate belite-type Various materials were used produce mixes for percentages belite, yeeliminite, other minerals in resultant Computer-based theoretical designed with SiO2, CaO, Al2O3, Fe2O3, SO3 then fired a laboratory furnace at 1250°C 20 min retention time. clinker samples characterized X-ray diffraction. quantification each sample was carried out Rietveld refinement. obtained results confirmed correlation between mineralogy chemical constituents mix. C4AF percentage increased an increase Fe2O3 percentage. C4A3$ content varied amounts SO3, CaO. mineral C2S had clear SiO2 Anhydrite changed These should aid determination optimum amount required development clinker.
