Abstract
In order to improve the grouting reinforcement effect of water prevention and control in coal mines,improve the performance of grouting materials,reduce the cost of grouting materials,and find a new way for the high-value comprehensive utilization of industrial solid waste at the same time,through a large number of laboratory experiments,this paper finally determined to use granulated blast furnace slag as the main raw material,desulfurization gypsum,cement clinker and admixture as auxiliary materials,developed a slag-based grouting material.By cross-comparing with slag cement for grouting,the physical properties of slag-based grouting material in fluidity,relative viscosity,slurry sedimentation rate,solidification state and mechanical properties were analyzed.The study provided a theoretical basis for the application of slag-based grouting materials in water prevention and control projects.关键词
