The invention relates to the technical field of curing agents, and particularly provides a soil curing agent, cured soil and application thereof. The first aspect of the invention provides a soil curing agent. The soil curing agent is prepared from the following raw materials in parts: 20-30 parts of a dispersing agent, 1-2 parts of a salt compound, 3-6 parts of a biological enzyme, 0.1-0.4 part of small molecular alcohol and 60-80 parts of a solvent. A sulfonate formaldehyde condensate with a specific content is selected as a dispersing agent, interacts with a salt compound, a biological enzyme and a solvent in a system, and can be subjected to ion adsorption and exchange with soil particles, so that the particles tend to be condensed, the soil particles are tightly bonded, and a reactionproduct can fully fill pores among the soil particles; the cured particles are easily compacted into a whole, so that the frost resistance, the compressive strength, the water-resistant stability andthe damp-heat aging resistance are favorably improved.
本发明涉及固化剂技术领域，更具体地，本发明提供了一种土壤固化剂、固化土及其应用。本发明第一方面提供一种土壤固化剂，制备原料包括20～30份分散剂、1～2份盐类化合物、3～6份生物酶、0.1～0.4份小分子醇、60～80份溶剂。选择特定含量的磺酸盐甲醛缩合物作为分散剂，与体系中的盐类化合物、生物酶以及溶剂相互作用，可与土颗粒进行离子吸附和交换，使颗粒趋于凝聚，使土颗粒之间紧密胶联，反应生成物可充分填充土颗粒间的孔隙，使固化颗粒易于压实成一体，有利于抗冻性能、抗压强度、耐水稳定性以及耐湿热老化性能的提升。
