Preparation method of phosphogypsum highway subgrade material
The invention provides a preparation method of an ardealite highway subgrade material. The preparation method comprises the following steps: heating common ardealite to 143-350 DEG C to generate calcined ardealite; taking the calcined ardealite as a base material, doping 5-20% of ordinary Portland cement, and uniformly mixing to obtain composite calcined ardealite; selecting the mixing proportion of the calcined ardealite or the composite calcined ardealite and the common ardealite for mixed reaction; and mixing into a uniform ardealite mixture by using mixing equipment according to the matching proportion, wherein the uniform ardealite mixture can be used as the highway subgrade material. And uniformly paving the phosphogypsum mixture, and compacting by rolling, so that the phosphogypsum mixture is subjected to a curing reaction to generate the phosphogypsum highway roadbed meeting the requirements of bearing capacity and environmental protection. The ardealite mixture is subjected to curing reaction to generate a synthetic material with certain strength through the mix proportion design of the ardealite mixture, so that the ardealite can be completely utilized, the problems of shortage of highway engineering building materials and high manufacturing cost are solved, and the pressure of environmental pollution caused by the ardealite is effectively relieved.
本发明提供了一种磷石膏公路路基材料制备方法，包括：将普通磷石膏加热143~350℃生成煅烧磷石膏；以煅烧磷石膏为基材掺入5~20%的普通硅酸盐水泥混合均匀制得复合煅烧磷石膏；选定煅烧磷石膏或复合煅烧磷石膏与普通磷石膏混合反应的配合比例；按照配合比例采用拌和设备拌和成均匀的磷石膏混合料即可作为公路路基材料。将磷石膏混合料摊铺均匀，碾压密实，使磷石膏混合料发生固化反应生成满足承载力和环境保护要求的磷石膏公路路基。本发明通过磷石膏混合料的配合比设计，使磷石膏混合料发生固化反应生成具有一定强度的合成材料，可实现磷石膏百分之百利用，缓解公路工程建筑材料紧缺、造价高的难题，有效化解磷石膏污染环境的压力。
