All-solid waste cementing material as well as preparation method and application thereof
The invention relates to the technical field of industrial waste recycling and road base materials, in particular to an all-solid-waste cementing material and a preparation method and application thereof. The all-solid-waste cementing material is prepared from, by mass, 22.5%-27.5% of phosphogypsum, 22.5%-27.5% of carbide slag and 45%-55% of superfine slag powder. The preparation method of the all-solid waste cementing material comprises the following steps: 1) stirring and mixing ardealite and carbide slag, and performing calcining to obtain a calcined product; 2) stirring and mixing the calcined product and the slag micro powder. The proportion design of the materials is reasonable; when the mixed calcined product of the ardealite and the carbide slag is mixed with the superfine slag powder for use, the activity of the mixed calcined product is excited under the action of the superfine slag powder, and the mixed calcined product is subjected to hydration reaction and pozzolanic reaction under the action of water, so that the roadbed and the pavement are cured and hardened by the reactions, the reaction product can also be filled into gaps of the roadbed pavement, so the structural strength of the roadbed pavement is improved.
本发明涉及工业废弃物资源化及公路基层材料技术领域，尤其是涉及一种全固废胶凝材料及其制备方法和应用，该全固废胶凝材料按质量百分数计，包括22.5％～27.5％磷石膏、22.5％～27.5％电石渣、45％～55％的矿渣微粉，该全固废胶凝材料的制备方法包括以下步骤：1)将磷石膏与电石渣经搅拌混合后，煅烧得到煅烧物；2)将煅烧物与矿渣微粉搅拌混合。本发明各材料配比设计合理，利用磷石膏、电石渣的混合煅烧物与矿渣微粉混合使用时，混合煅烧物在矿渣微粉的作用下活性被激发，在水的作用下发生水化反应及火山灰反应，这些反应使路基路面发生固化和硬化的同时，反应产物还可以填充至路基路面的缝隙中，从而增加了路基路面的结构强度。
