Alite-ye'elimite clinker is a high cementing clinker that is prepared by introducing calcium sulfoaluminate, a non-silicate mineral, into cement clinker. The industrial residue was used to produce cement clinker. The relationship of the aluminate modulus (IM) and the mineral composition and mechanics of tricalcium silicate-rich sulfur aluminate cement is reported. The effects of the aluminate modulus on the phase compositions, morphology and compressive strength were investigated. The phase morphology was analyzed by optical microscopy. The results show that the increase of IM in the clink can accelerate the formation of calcium sulfoaluminate; calcium sulfoaluminate can form at the temperature of 1250 °C when the IM value is lower than 2.50, while it exists at a temperature of 1300 °C without reheating when the IM value is higher than 2.50.
