Lead-zinc smelting slag-based cementing material as well as preparation method and application thereof
The invention relates to the technical field of solid waste recycling, and discloses a lead-zinc smelting slag-based cementing material as well as a preparation method and application thereof. The lead-zinc smelting slag-based cementing material is prepared from the following raw materials in parts by mass: 25 to 55 parts of lead-zinc smelting slag, 8 to 30 parts of cement clinker, 11 to 45 parts of exciting agent, 0 to 7 parts of calcium chloride and 0.05 to 0.25 part of reinforced fiber. According to the lead-zinc smelting slag-based cementing material, the 3d compressive strength is larger than or equal to 2.3 MPa, the 28d compressive strength is larger than or equal to 21.9 MPa, and the mechanical property is excellent; the cementing material is prepared by taking the lead-zinc smelting slag as a raw material, so that the problems that the lead-zinc smelting slag is high in yield and difficult to consume are solved; the consumption of cement is reduced, and the material cost is reduced; the problems of energy consumption and environmental pollution caused by cement production are reduced, and the environmental and economic benefits are high; the preparation method of the material is simple; the material can meet the application requirements of mine goaf or roadbed filling.
