Universal rock and soil curing agent and preparation method thereof

Abstract

The invention relates to a universal rock and soil curing agent and a preparation method of the universal rock and soil curing agent and aims at solving the problem of poor curing quality of the existing curing agent. The universal rock and soil curing agent comprises a powdery mixture formed by mixing the following raw materials: calcium oxide, silicon dioxide, aluminium oxide, sulfur trioxide, magnesium oxide and ferric oxide. The universal rock and soil curing agent is characterized in that raw materials also comprise viscous polymers and materials with cinerite activity or powdery materials with viscosity after sintering and water meeting, wherein the viscous polymers account for 2 to 8 percent of the total weight of the powdery mixture, the materials with cinerite activity or the powdery materials with viscosity after sintering and water meeting account for 5 to 20 percent of the total weight of the powder mixture, the raw materials also comprise compound body additional adding agents, the compound body additional adding agents account for 1 to 3 percent of the total weight of the powdery mixture and are formed by mixing the following raw materials in percentage by weight or are the following raw materials in percentage by weight: 0 to 100 percent of NaOH and 100 to 0 percent of water reducers. The preparation method comprises the following steps that: the raw materials according to the weight mixing ratio are put into a powder body mixing machine, the pre-mixing is firstly carried out, then, the major mixing is carried out, and the materials are sufficiently and uniformly mixed. The universal rock and soil curing agent and the preparation method have the advantages that the rock and soil curing quality is good, the cost is low, the application range is wide, various inorganic solid waste materials can be cured, waste materials are changed into useful materials, the cost performance is high, economic benefits and environment benefits are obvious, and popularization and application prospects are wide.

Description

technical field [0001] The invention relates to a curing agent, in particular to a universal rock soil curing agent and a preparation method thereof. technical background [0002] At present, industrial waste particles have brought a series of problems to the environment, ecology, and society, and seriously hindered the development of a two-oriented society. In terms of engineering, the sand and gravel building materials needed to build roads and houses in many areas are scarce, resulting in abnormally high construction costs. Urban demolition of old buildings and construction of new buildings produce a large amount of construction waste, which also seriously affects urban development and the environment. If these wastes can be effectively utilized and turned into resources, it will bring huge wealth to the society. [0003] The defects of the prior art are: construction waste slag needs to be sorted and washed first, the cost is high, and secondary pollution is formed; ma...

Problems solved by technology

[0003] The defects of the prior art are: construction waste slag needs to be sorted and washed first, the cost is high, and secondary pollution is formed; many industrial wastes, such as alkali slag and light burning dust, have not effectively solved the expansion problem: the utilization tail in the filling mining method The technical economy of the tailings filling slurry prepared by the ore filling cementitious material is still not satisfactory to the mining enterprises; the tailings produced after the beneficiation of various metal and non-metal tailings in industrial mining are difficult to solidify with cement, even if some The curing agent can be cured, but the cured block is difficult to meet the needs of various engineering purposes
