Additive for muck solidification and preparation method thereof
The invention belongs to the technical field of roadbed solidification, and relates to an additive for muck solidification and a preparation method thereof. The cement-based composite material comprises the following components in parts by weight: 15-25 parts of a mineral admixture, 5-10 parts of modified diatomite, 1-1.5 parts of an exciting agent and the balance of cement, and the total mass of all the components is 100 parts. The curing material is prepared by compounding the exciting agent, the steel slag and the slag powder, and the two are combined to improve the early and later strength of the cured soil at the same time. Meanwhile, by modifying the diatomite, the dispersity of the diatomite and the carbonaceous powder in a cementing material is improved, the adhesive property of the cement is improved, and by utilizing the property that the diatomite and sodium polyacrylate are gathered with calcium oxide in the cement in a water environment to generate a water-insoluble crystalline substance, the strength and water erosion resistance of the solidified soil are improved.
本发明属于路基固化技术领域，涉及一种渣土固化用添加剂及其制备方法。按照重量份数计算，包括如下组分：15~25份矿物掺合料、5~10份改性硅藻土、1~1.5份激发剂，以及余量的水泥，各组分的总质量为100份。本申请使用激发剂和钢渣、矿渣粉复配制备固化材料，两者结合作用，能够同时提高固化土的早、后期强度。同时通过对硅藻土进行改性，提高硅藻土与碳质粉末在胶凝材料中的分散性，提高水泥的粘结性能，利用硅藻土，聚丙烯酸钠在水环境中和水泥中的氧化钙集合，生成不溶于水的结晶物质的性质，从而提高固化土强度和抗水侵蚀能力。
