Abstract

Effect of TiO₂ content on the burnability of clinker with high C₃S were investigated by determination of free lime in final product, and the clinker phase formation, microstructural features of C₃S and the solubility of TiO₂ in C₃S were further studied by XRD, SEM/EDS analysis. TiO₂ accelerates the combination of free lime in the samples, free lime content decreases obviously with TiO₂ increasing up to 2% and almost remains above 2%. A new phase CaO·TiO₂ was found when TiO₂ was up to 3%, and samples with TiO₂ displayed well-formed uniform size hexagonal C₃S crystal. The limit of solubility of TiO₂ in C₃S at 1400 °C is about 1.7%.
