| 摘 要： | 利用脱硫石膏的胶凝性能,将之与火电厂废弃物按一定比例混合后,能产生与水泥水化产物相似的成分。在保证充填体抗压强度的情况下,脱硫石膏能取代 10% ~12%的水泥以胶结尾砂充填,从而降低充填成本。并对脱硫石膏胶结尾砂的作用机理进行了探讨。

| Abstract: | By using the gel property of FGD -gypsum,mixing it with waste material from thermal power plant in a certain proportion can generate a component similar to hydrated product of cement. In the case of assuring the compressive strength of filling -object,desulfurization gypsum can replace 10～12 percent of cement to cement filling -tailings so that reduce the cost of filling. The paper has discussed the mechanism of desulfurization gypsum cementing tailings as also. |
