脱硫石膏不同脱水程度对水泥性能影响的研究

Effect of degree of dehydration of desulfurized gypsum on properties of cement

通过实验室小磨试验,研究了脱硫石膏在不同脱水程度下对水泥性能的影响。结果表明,脱硫石膏无论以何种形态作为水泥缓凝剂使用,均不会引起水泥的急凝。但不同脱水程度的脱硫石膏对水泥的性能有不同程度的影响。

Application of testing mill in lab, the effect of desulfurization gypsum on the performance of cement in different degree of dehydration was studied. The results showed that the desulfurization gypsum would not cause false setting of cement when desulfurization gypsum was used as cement retarder. But the different degree of dehydration of desulfurization gypsum would have different influence on the properties of cement.
