Cementing material and application thereof

The invention relates to the technical field of solid waste resource utilization, and discloses a cementing material and application thereof. The cementing material is prepared from the following raw materials in parts by mass: 40 to 70 parts of solid waste aggregate, 15 to 20 parts of cement clinker, 11 to 30 parts of mineral admixture, 2 to 10 parts of admixture and 0.05 to 0.25 part of reinforced fiber. According to the cementing material provided by the invention, the industrial solid waste is used as the aggregate, so that the resource utilization of the industrial solid waste is realized, the cement consumption is reduced, the environmental pollution caused by cement production is favorably reduced, the material cost is low, the mechanical property is excellent, and the economic value is high. The fine tailings cemented filling material obtained by mixing the cementing material and the fine tailings is high in compressive strength, low in cement-sand ratio of the cementing material and the fine tailings
