Embodiment 1

[0032] Embodiment 1, a kind of soil solidifying agent

[0033] Described soil solidifying agent comprises following component and parts by weight thereof:

[0034] 20 parts of 2-acrylamido-2-methylpropanesulfonic acid, 5 parts of anionic polyacrylamide, 5 parts of sodium sulfate, 10 parts of calcium phosphate, 5 parts of sodium gluconate, 5 parts of sodium lignosulfonate, sodium silicate 4 parts, 2 parts of sodium hydroxide and 40 parts of water.

[0035] Preparation:

[0036] S1 Take half of the amount of water and stir 2-acrylamido-2-methylpropanesulfonic acid, sodium sulfate, calcium phosphate and sodium lignosulfonate evenly to obtain mixture I;

[0037] S2 Take the remaining water and stir the polyacrylamide, polysaccharide and sodium silicate evenly to obtain mixture II;

[0038] S3 Mix sodium hydroxide with the mixture I obtained in step S1 and the mixture II obtained in step S2 uniformly, and dry at 40° C. to obtain.

Embodiment 2

[0039] Embodiment 2, a kind of soil solidifying agent

[0040] Described soil solidifying agent comprises following component and parts by weight thereof:

[0041] 30 parts of 2-acrylamido-2-methylpropanesulfonic acid, 24 parts of anionic polyacrylamide, 18 parts of sodium sulfate, 20 parts of calcium phosphate, 18 parts of sodium gluconate, 10 parts of sodium lignosulfonate, sodium silicate 8 parts, 6 parts of sodium hydroxide and 50 parts of water.

[0042] The preparation method is similar to Example 1.

Embodiment 3

[0043] Embodiment 3, a kind of soil solidifying agent

Abstract

The invention belongs to the technical field of stabilizers and particularly relates to a soil stabilizer and a preparation method thereof. The soil stabilizer mainly comprises 2-acrylamido-2-methylpropane sulfonic acid, polyacrylamide, sodium sulfate, calcium phosphate, a polysaccharide, sodium lignosulfonate, sodium silicate, sodium hydroxide and water. The formulation of the soil stabilizer provided by the invention is reasonable and scientific in matching and may effectively shorten stabilizing time of soil and enhance soil stabilizing and hardening effects, and experiments show that a solid brick obtained by stabilizing may be as hard as and even harder than a red brick, has waterproof performance also meeting the waterproof standards of red bricks and is an ideal soil stabilizer.

Description

technical field [0001] The invention belongs to the technical field of curing agents, and in particular relates to a soil curing agent and a preparation method thereof. Background technique [0002] Soil stabilizer is a new type of engineering material used to solidify various soils after a variety of inorganic materials or organic materials are processed by a certain production process. Soil stabilizer has the effect of directly cementing the surface of soil particles in the soil or reacting with clay minerals to form gelatinous substances at room temperature, which can change the composition of the soil and the engineering properties of the soil, thereby improving the strength of the soil and improving Soil compactness. [0003] With the development of society, the demand for engineering construction in various industries is also increasing, while traditional engineering construction requires a large amount of natural resources, blasting mountain gravel, digging rivers an...
