Abstract: 
Municipal Solid Waste Incineration (MSWI) fly ash was used as a major cement raw material in producing sulfoaluminate cement-based materials (SACBM) in laboratory. In this paper, the sintering system and morphology of the sulfoaluminate cement clinker, the properties of the SACBM, including compressive strength, setting time, drying shrinkage resistance, carbonization resistance and sulfate corrosion resistance, were investigated. Results show that sulfoaluminate cement clinker can be sintered properly under the temperature of 1200-1250. Compared with composite Portland cement P.C32.5R (C-I) and commercial sulfoaluminate cement (C-II), the resistance properties of SACBM to drying shrinkage and carbonization are better than that of C-I but lower than that of C-II. The SACBM also have an excellent property of sulfate corrosion resistance and the resistance coefficient increases with the time prolonging.
