Composite curing agent for high liquid limit soil as well as use method and application of composite curing agent
The invention provides a composite curing agent for high liquid limit soil as well as a use method and application of the composite curing agent. The composite curing agent for the high liquid limit soil is prepared from the following raw materials in percentage by weight: 35 to 45 percent of Portland cement, 35 to 43 percent of slag powder, 8 to 11 percent of quick lime and 9 to 13 percent of lignin. By adopting the composite curing agent for the high liquid limit soil, the CBR value of the improved high liquid limit soil is remarkably increased, the requirements of roadbed filler can be met, and the problem that the high liquid limit soil cannot be used for the roadbed filler is solved. According to the curing agent, the use amount of cement is reduced by adding slag powder, quick lime and lignin, so that industrial byproducts of slag and lignin are turned into wealth, waste of resources is avoided, meanwhile, the construction cost is reduced, and the concept of sustainable development is met.
本发明提供了一种高液限土用复合固化剂及其使用方法和应用，该高液限土用复合固化剂由以下重量百分比的原料组成：硅酸盐水泥35～45％，矿渣粉35～43％，生石灰8～11％，木质素9～13％。采用本发明高液限土用复合固化剂，使改良后的高液限土的CBR值显著提高，并能满足路基填料要求，解决高液限土不能用于路基填料的问题。而本发明固化剂通过添加矿渣粉、生石灰、木质素来减少水泥用量，使工业副产品矿渣、木质素实现变废为宝，避免了资源的浪费同时降低施工成本，符合可持续发展理念。
