磷石膏、粉煤灰胶结材的研究

Study on cementitious material produced by phosphogypsum and fly ash

利用生石灰中和磷石膏中的可溶性磷 ,既消除了可溶性磷的危害 ,为胶结材提供了CaO ,同时可大大降低胶结材生产中的能耗。胶结材可用于制建筑抹灰砂浆等 ,强度和耐水性良好 。

The advantage of using calcined lime to neutralize soluble phosphorus in phosphogypsum is that it can eliminate the harm of soluble phosphorus and supply CaO for cementitious material and decrease the power consumption in the production.The cementitious material can be used to produce building mortar.
