Effect of sulfate content and synthesis conditions on phase composition of belite-ye'elimite-ferrite (BYF) clinker
BYF cements are a promising alternative to Portland cement due to their lower CO2 emissions and energy demand. However, it is essential to assess how production parameters affect BYF clinker composition. In this study, clinkers with varying SO3 content were synthesized at temperatures of 1100–1400 °C and retention times of 15–120 min. The mineralogy of the produced clinkers was analyzed using X-ray powder diffraction with Rietveld phase analysis. According to the results, firing temperatures of 1300–1350 °C, retention times of 30–60 min, and excess SO3 are needed to obtain the desired clinker composition. It was proved that SO3 contributed to the stabilization of β-C2S and the formation of ye'elimite. Additionally, increasing SO3 resulted in higher contents of cubic ye'elimite relative to orthorhombic. It was demonstrated that the level of Fe2O3 incorporated into C4A3$-c increased with the increase of SO3, as indicated by the decrease in C4AF and unit cell volume.
