preparation example Construction

[0031] A preparation method of an inorganic high molecular polymer soil solidifying agent, comprising the following steps:

[0032] Step 1: After mixing the aluminosilicate material with the required solidified loess, place it in a dry powder mixer and stir evenly, preferably for 10 minutes, to obtain mixture A, wherein the aluminosilicate material and the required solidified loess are preferably in accordance with the quality The ratio is 1:22.1 mixing;

[0033] Step 2: standing and activating the alkali activator solution, sealed and packaged for use; the preparation method of the alkali activator solution includes the following steps:

[0034] 1) mixing sodium silicate powder and sodium hydroxide in a ratio of 2.95-5.97:1 by mass;

[0035] 2) After fully stirring, add water to prepare a solution with a sodium silicate concentration of 40% and a sodium hydroxide concentration of 4.22 mol / L in the alkali activator solution, and then stand for activation for 24 hours.

[003...

Embodiment 1

[0040] Take 26.8 parts by mass of metakaolin, 22.4 parts by mass of sodium water glass, and 1 / 250 part by mass of sulfonated oil. Mix the metakaolin and the required solidified loess according to the proportion (mass ratio 1:22.1), stir evenly in a dry powder mixer for 10 minutes to obtain a mixture one; spray the sodium water glass solution on the surface of the mixture one, mix and add a mixture of sulfonated oil. Aqueous solution, adjust the water content to the optimal water content, after fully stirring and mixing, and then let the stewed material stand for 10 minutes, until the water in the mixture is evenly dispersed; start the demoulding of the product and carry out maintenance under standard conditions.

Embodiment 2

[0042] Take 24 parts by mass of metakaolin, 24.6 parts by mass of sodium water glass, and 1 / 150 part by mass of sulfonated oil. Mix the metakaolin and the required solidified loess according to the proportion (mass ratio 1:22.1), stir evenly in a dry powder mixer for 10 minutes to obtain a mixture two; spray the sodium water glass solution on the surface of the mixture two, mix and add a mixture of sulfonated oil. Aqueous solution, adjust the water content to the optimal water content, after fully stirring and mixing, and then let the stewed material stand for 10 minutes, until the water in the mixture is evenly dispersed; start the demoulding of the product and carry out maintenance under standard conditions.

Abstract

The invention discloses an inorganic high-molecular polymer soil stabilizer and a preparation method thereof. The inorganic high-molecular polymer soil stabilizer comprises a solid component raw material and a liquid component raw material, the solid component raw material comprises an aluminosilicate material; the liquid component raw materials comprise an alkali activator solution and sulfonated oil. According to the inorganic high-molecular polymer soil stabilizer and the preparation method, the curing strength and the dry shrinkage deformation resistance of cured soil are improved, and the problem that the strength attenuation is large after the soil stabilizer is soaked in water for a long time is solved; the preparation method is simple, the curing agent can be distributed more uniformly in the soil through the method, the curing effect of the inorganic high-molecular polymer is exerted to the maximum extent, and the preparation method is well compatible with existing construction machinery during engineering application.

Description

technical field [0001] The invention relates to the technical field of soil curing agents, in particular to an inorganic high molecular polymer soil curing agent and a preparation method. Background technique [0002] More and more construction projects require artificial foundations to meet the requirements of buildings on foundations. In Gansu and Qinghai, there are widely distributed soils with poor engineering properties such as collapsible loess and saline soil. For the construction projects in the collapsible loess and saline soil areas, the field floor shall be closed. At present, the commonly used methods of yard sealing in engineering are lime-soil replacement method and cement-soil replacement method. In recent years, due to their own defects, construction quality or unreasonable design and other factors, some projects have experienced different degrees of foundation uplift and expansion within a few years after completion, causing great damage to buildings.
