Substitute anhydrous gypsum for dihydrategypsum in Potland cement production to study the effect of anhydrous gypsum on performance of Potland cement.
研究了在硅酸盐水泥中使用硬石膏完全代替二水石膏对硅酸盐水泥性能的影响。
2
It reduces dehydration temperature and solubility of dihydrategypsum, makes gypsum crystals thick and wide, and reduces the strength of hardened body.
可溶磷降低二水石膏脱水温度和液相过饱和度，使二水石膏晶体粗化，硬化体强度降低。
3
The influences of adding calcined gypsum instead of dihydrategypsum and adding a little limestone on the physical properties of cement were investigated.
