Abstract
This is an essay in the field of ceramics and composites.To solve the problems of high-cost for cement cementitious material and low strength of cement filling body at the later stage in a lead-zinc mine,abundant slag solid waste resources were adopted and low-cost slag cementitious materials were developed in this paper to meet the quality requirement of mine fillings.After physical and chemical analysis of tailings,slag and cement clinker,the physical and chemical analysis of tailings,slag and cement clinker was carried out.Then,through the filler slurry slump test and the exploration test of the ratio of slag cementitious material,it is determined that the slurry concentration satisfying the fluidity is about 70%,and the ratio of slag to cement clinker is 2～4.The strength,bleeding rate and coagulation characteristics of filling body with different proportions of slag cementitious materials were investigated by comprehensive test.The results show that the ratio of slag cementitious material is 75%～80%slag and 20%～25%cement clinker,the filling body can meet the filling quality requirements of 0.5～3.5 MPa compressive strength and the filling slurry bleeding rate is less than 5%.关键词
