摘 要：To explore the mechanisms of filter mud （FM） in the portland cement clinker formation, and to make effective use of FM in the cement production as lime-based raw materials, the influences of FM on the apparent activation energy of calcium carbonate decomposition, liquid phase amount, crystalline phase and tricalcium silicate polymorphism were investigated by TA, SEM and XRD. The experimental results show that FM can reduce apparent activation energy of calcium carbonate decomposition, and increase liquid phase amount. Appropriate FM replacement ratios are useful to promoting the C3S formation and heightening the C3S content. New phases of α-C2S and C2S?0.5Ca3 （PO4）2 can be found in the clinkers while the ratios are above 15%. In addition, impurities in FM can induce the C3S polymorph to transform.
