Abstract

The invention discloses a soil stabilizing agent, and belongs to the technical field of land control. The soil stabilizing agent is prepared from the following raw materials: modified diatomite, fly ash, cement, gypsum powder, perlite powder, titanium oxide, surface active agents, tetramethylammonium hydroxide, polyacrylamide, hydroxypropyl methylcellulose, polycarboxylate, polyoxyethylene octylphenol ether, and isopropenyl acetate-ethyl isothiocyanate copolymers. The soil stabilizing agent provided by the invention has the advantage that the soil intensity, the no confined compressive strength, the water stability and the flushing resistance can be obviously improved.

Description

technical field [0001] The invention belongs to the technical field of land treatment, and in particular relates to a land stabilizer. Background technique [0002] Soil stabilizer is a new type of soil stabilization material. It changes the arrangement and combination of soil molecules to form a network between molecules that water cannot pass through, and then uses the viscosity of the soil itself to stabilize the soil, improve soil bearing capacity, and prevent water penetration. , The purpose of accelerating the natural fossilization of soil. Therefore, the use of land stabilizers can play a good role in solving ecological and environmental problems such as soil erosion and land desertification. By the 1980s, people had fully understood the existing synthetic polymer soil structure stabilizers. By 1996, polyacrylamide had been widely used as a soil-stabilizing water-retaining agent in the United States. At the same time, for the consideration of cost reduction and env...
