Method for in-situ modification and curing of lignin-based composite curing agent
The invention relates to the field of solidification and improvement of engineering muck, in particular to an in-situ modification and solidification method of a lignin composite curing agent, which comprises the following steps: uniformly dry-mixing engineering muck to be solidified with cement, calculating the required water addition amount according to the optimal water content of the engineering muck, dissolving water glass and lime in water to generate amorphous calcium silicate, and then adding the lignin composite curing agent into the water to form the lignin composite curing agent. The method comprises the following steps: mixing lime, sodium silicate and engineering residue soil, dissolving sodium lignin sulfonate, uniformly mixing a suspension containing lime, sodium silicate and sodium lignin sulfonate with the engineering residue soil, compacting to the maximum dry density of the mixed improved soil, and curing for not less than 7 days. And no secondary pollution is caused.
本发明涉及工程渣土固化改良领域，尤其涉及一种木质素复合固化剂原位改性及固化的方法，它包括将需要固化的工程渣土与水泥干混均匀，按照工程渣土的最佳含水率计算所需加水量，将水玻璃和石灰先溶于水中生成无定形的硅酸钙，再溶入木质素磺酸钠，最后将含有石灰、水玻璃和木质素磺酸钠的悬浮液与工程渣土拌合均匀，压实至该混合改良土的最大干密度，并养护不少于7天，通过本申请的技术方案固化工程建设渣土具有低成本、操作简易、物料效率高，且无二次污染的优点。
