Carbon sequestration soft soil curing agent as well as preparation method and application thereof

The invention relates to a carbon sequestration soft soil curing agent which comprises the following components in parts by weight: 30-50 parts of blast furnace slag, 5-16 parts of fly ash, 4-15 parts of waste concrete, 8-20 parts of steel slag, 5-16 parts of LF furnace refining slag, 5-10 parts of desulfurized gypsum, 8-15 parts of CaO, 1-2 parts of triethanolamine residue and 1-3 parts of potassium sulfoaluminate dodecahydrate. Wherein the triethanolamine residues are solid residues generated in the production process of triethanolamine. The product and the application method have the series of advantages of low carbon, carbon sequestration, high strength development and wide applicability in soft soil reinforcement engineering, various solid waste resources are greatly utilized, meanwhile, CO2 gas is creatively used for curing, the low carbon and carbon sequestration effects are achieved, and the application prospect is wide. 本发明涉及一种固碳软土固化剂，按照重量计，其包含以下组分：30-50份高炉矿渣、5-16份粉煤灰、4-15份废弃混凝土、8-20份钢渣、5-16份LF炉精炼渣、5
