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 ℃ is about 1.7%.
