Abstract In view of the problems of compression bleeding and affecting the use effect of ultra-high water materials, the properties of industrial solid wastes such as fly ash, granulated blast furnace slag powder and iron tailings sand were studied. Combined with the characteristics of super -high water materials, a large number of experiments were carried out to improve the properties of super-high water materials and realize the comprehensive utilization of industrial solid wastes by adding appropriate amount of industrial solid wastes into super-high water filling materials.
