Adding different types and amounts of water reducing agent to Dolomite-based magnesium sulfate cement (DBMSC), and analysing the effect of water reducing agent on DBMSC by studying its setting time, water reduction effect and mechanical strength. on the one hand, Experimental results show that adding water reducing agent to DBMSC has a retarding effect on dolomitic magnesium sulfate cement, and reduces the hydration heat of cement; on the other hand, the water reduction effect of the water reducing agent on DBMSC prepared by light burning dolomite is not too obvious, and even the mechanical strength of DBMSC is lowered.
