Embodiment 1

[0019] A soil stabilizer is composed of the following raw materials in parts by weight:

[0020] Lime 5 Gypsum 39 Slag 36

[0021] Cement clinker 55 Activator 1;

[0022] Wherein: the stimulating agent is composed of 85% of lignin, 12% of sulfonate and 3% of sodium sulfate.

[0023] After mixing the above-mentioned various materials in proportion, use a ball mill for grinding treatment to obtain a particle size with a specific surface area of ​​250-800m 2 / Kg.

Embodiment 2

[0025] A soil stabilizer is composed of the following raw materials in parts by weight:

[0026] Lime 2 Gypsum 50 Slag 25

[0027] Cement clinker 65 Activator 1.3.

[0028] Wherein: the stimulating agent is composed of 85% of lignin, 12% of sulfonate and 3% of sodium sulfate.

Embodiment 3

[0030] A soil stabilizer is composed of the following raw materials in parts by weight:

[0031] Lime 8 Gypsum 28 Slag 46

[0032] Cement clinker 46 Activator 0.5.

[0033] Wherein: the stimulating agent is composed of 85% of lignin, 12% of sulfonate and 3% of sodium sulfate.

[0034] The method of using the above soil stabilizer: crush the soil, sieve, clear the sundries, and then determine the amount of stabilizer added according to the actual situation, calculated according to 5% to 25% of the dry weight of the soil to be stabilized, add soil After adding body stabilizer, mix evenly.

[0035] The soil stabilizer is much better than ordinary portland cement and soil curing agents on the market under the same conditions in terms of strength, frost resistance and dryness resistance. It has the characteristics of high strength, convenient construction and excellent durability; At the same time, the stabilizer is convenient in compounding, and can also consume industrial wast...

Abstract

The invention discloses a soil body stabilizing agent, composed of following materials by weight: 2-8 parts of lime, 28-50 parts of gypsum, 25-46 parts of slag and 46-65 parts of cement clinker and 0.5-1.3 parts of excitant which comprises 85% of xylogen, 12% of sulphonate and 3% of sodium sulfate. The soil body stabilizing agent has easy obtained materials and is suitable for the project base process such as reservoir, large dam, pond and soft foundation, various sullage curing process, sea filling project, oil field slime pulp process and the like. The stabilized soil body has good compression resistant, impervious and antifreezing performance; the building cost of projects is low and the construction is convenient.

Description

technical field [0001] The invention relates to a soil stabilizer for municipal construction. Background technique [0002] When the soil stabilizer is mixed with the soil containing a certain amount of water, a series of physical and chemical reactions are likely to occur. First, a large number of needle-like crystals rich in crystal water are formed in the soil, interspersed in the pores of soil particles to form a strength skeleton; secondly, The silicate hydrate is filled in the strength skeleton to further compact the curing system; finally, under the action of the activator, the soil stabilizer reacts chemically with some soil particles, so that the reinforced soil has good irreversible durability. [0003] The mechanism of action of the soil stabilizer includes a physical-mechanical stage, a chemical stage, and a physical-chemical stage. The physical-mechanical stage is the simplest and most basic method for solidifying soil; During the process, its own components un...
