Solid waste phosphogypsum roadbed improvement soil stabilizer and preparation method thereof
The invention relates to the technical field of soil stabilizers, in particular to a solid waste phosphogypsum roadbed improvement soil stabilizer and a preparation method thereof. The curing agent comprises the following raw materials in percentage by mass: a curing material is prepared from a curing mixture and a stabilizer in proportion; the curing mixture comprises 7% of cement, 2% of lime, 10% of calcined ardealite and 81% of ardealite; the stabilizer comprises sodium silicate, sodium metaaluminate and calcium chloride; and the ratio of the curing material to the soil is self-adaptively matched. By means of the method, the early performance and the water stability of the solidified soil are well improved, the internal structure of a sample is more compact, and therefore the strength is greatly improved. The preparation method is used for preparing the solid waste phosphogypsum roadbed improvement soil stabilizer.
本发明涉及土壤固化剂技术领域，尤其涉及一种固废磷石膏路基改良土壤固化剂及其制备方法。该固化剂包括如下按质量百分数计的原料：固化材料由固化拌合物和稳定剂配比而成；固化拌合物包括水泥7%、石灰2%、煅烧磷石膏10%、磷石膏81%；稳定剂包括硅酸钠、偏铝酸钠、氯化钙；固化材料与土壤的比例自适应配比。通过上述，较好地提高固化土的早期性能和水稳性能，使得试样内部结构更加的密实，因此强度也得到了大幅度的提升。该制备方法用于制备上述一种固废磷石膏路基改良土壤固化剂。
