Belite-C2.75B1.25A3$ cement was belite-rich cement containing C2.75B1.25A3$ mineral of 9wt%.Due to the differences of dissolution velocity and element sulfur content, the effects of gypsum category on the setting time and early mechanical property of belite-C2.75B1.25A3$ cement were investigated in paper by means of XRD,SEM, EDS and etc.The experimental results showed that lemon gypsum had faster dissolution velocity than any other type of gypsum.Consequently, the initial and final setting time of cement with lemon gypsum was all earlier than that of cement with any other kinds of gypsum.But, the compressive strength of cement with phosphogypsum cured for 1day, 3days and 7days were the highest.It was in accordance with the analysis of XRD, SEM and EDS, which showed that more content of AFt was formed in cement with phosphogypsum gypsum than that of cement with any other type of gypsum.
