Phosphogypsum composite soil curing agent with good curing performance, preparation method of phosphogypsum composite soil curing agent and derivative cured soil
The invention relates to the technical field of soil reinforcement, and discloses an ardealite composite soil curing agent with good curing performance, a preparation method of the ardealite composite soil curing agent and derivative cured soil. The ardealite composite soil stabilizer is prepared by mixing the following components in parts by mass: 20-30 parts of ardealite, 18-33 parts of cement, 32-54 parts of slag and 3-7 parts of quick lime. When the phosphogypsum composite soil curing agent is used for curing polluting silt, the phosphogypsum composite soil curing agent, water and the polluting silt are mixed, stirred and cured, and the compressive strength of the obtained cured soil is larger than or equal to 2 MPa; the adding amount of the polluting silt is 5-10 times of the mass of the phosphogypsum composite soil stabilizer. According to the invention, the problem of treatment of the phosphogypsum as polluted solid wastes in the phosphating industry is successfully solved, and heavy metal ions and polluting silt are successfully cured by using the curing agent with high curing performance, so that air pollution caused by dust flying and water and soil pollution caused by the heavy metal ions are prevented.
本发明涉及土壤加固技术领域，公开了一种固化性能好的磷石膏复合土壤固化剂及其制备方法和衍生固化土。所述磷石膏复合土壤固化剂包括以下质量份混合而成：磷石膏20～30份，水泥18～33份，矿渣32～54份，生石灰3～7份；在将所述磷石膏复合土壤固化剂固化污染性粉土时，将所述磷石膏复合土壤固化剂与水、污染性粉土混合搅拌并养护所得固化土抗压强度大于或等于2MPa；所述污染性粉土加入量为所述磷石膏复合土壤固化剂质量的5～10倍。本发明成功解决了磷石膏作为磷化工业的污染固体废弃物的处理问题，并且用固化性能高的固化剂成功固化重金属离子和污染性粉土，防止粉尘飞扬污染空气和重金属离子污染水土。
