Problems solved by technology

[0002] At present, the backfill materials for construction projects in my country are still plain soil, lime soil, and stone salt as the main backfill materials. These materials have a single composition, low strength, and easy to generate dust during backfill. They are not suitable for areas with high environmental protection requirements. After backfilling, the material will crack due to the ambient temperature, and it will produce uneven settlement due to the impact of compaction.

Abstract

The invention discloses a composite liquid soil curing agent and a preparation method thereof. The curing agent comprises a main material, a dispersing agent, an emulsifying agent, a surface active component, a flocculating agent, a stabilizing agent, a water reducing agent, an anti-freezing agent, a defoaming agent and water. Wherein the curing agent main material is one or more of lauryl sodium sulfate and diethanolisopropanolamine, the dispersing agent is one or more of polyoxyethylene and polyethylene glycol, and the emulsifying agent is one or more of sucrose fatty acid ester, OP-15, sodium dodecyl sulfate, sodium dodecyl sulfate, sodium dodecyl sulfate and sodium dodecyl sulfate. The surface active component is sodium alpha-olefin sulfonate, sodium alcohol ether sulphate and cocamidopropyl dimethylamine oxide, the flocculating agent is one or more of polyacrylamide, sodium polyacrylate and calcium polyacrylate, the stabilizer is sorbitol, the water reducing agent is sodium polycarboxylate, the antifreeze agent is glycerol, and the dispersant is sodium dodecyl sulfate. The defoaming agent is an organic silicon defoaming agent. The composite liquid soil stabilizer provided by the invention is environment-friendly, pollution-free, small in shrinkage deformation, good in low-temperature stability, high in compressive strength, convenient in construction process, capable of shortening the construction period and suitable for curing treatment of backfill of constructional engineering.

Description

Technical field [0001] The present invention relates to a composite liquid soil curing agent and a preparation method thereof, especially suitable for the curing treatment of construction engineering backfilling, belonging to the field of building materials technology. Background [0002] At present, China's construction project backfill materials are still based on plain soil, ash soil, salt nitrate these three materials as the main backfill materials, such materials have a single composition, low strength, easy to produce dust when backfilling, not suitable for areas with high environmental protection requirements, after backfilling the material will crack by the ambient temperature, affected by compaction will produce uneven settlement. Contents of the Invention [0003] Object of the present invention is to overcome the shortcomings of the above-mentioned prior art and to provide a harmless soil, no pollution, small shrinkage deformation, good low temperature stability, high...
