preparation example Construction

[0025] Another kind of specific embodiment of the present invention provides the preparation method of above any one solidified lightweight soil, comprises the following steps:

[0026] (1) Prepare raw materials, mould, stirring pot;

[0027] (2) Weigh dry soil, that is, alkali slag and soil, in a stirring pot, and the mass ratio of alkali slag and soil is 40:60-70:30. Based on dry soil, weigh 70-80% of water, 11-19% of cement, 4-10% of lime, 8-12% of fly ash, 0.3-0.7% of acrylamide, and 0.3% of the amount of acrylamide for ammonium persulfate. Aluminum powder 0.7-1.1%.

[0028] (3) Mix dry soil, cement, lime, fly ash and aluminum powder and stir evenly.

[0029] (4) Dissolve the acrylamide and ammonium persulfate weighed in step (2) in water first, then pour them into step (3) and stir thoroughly. This step is a critical step, the acrylamide gelatinous block in the mud must be stirred, otherwise the sample will crack after molding.

[0030] (5) Pour the fully stirred slur...

Embodiment 1

[0033] 1 Prepare the ingredients:

[0034] Weigh dry soil (alkali slag ratio soil 50:50),

[0035] In terms of dry soil weight, weigh 15% cement, 6% quicklime, 10% fly ash, 0.7% aluminum powder,

[0036] In terms of dry soil weight, weigh 80% water,

[0037] Based on dry soil weight, weigh 0.3% acrylamide, dissolve in water

[0038] Based on the weight of acrylamide, weigh 0.3% ammonium persulfate and dissolve it in water.

[0039] 2 Prepare the mold: the size is 46mm in inner diameter and 80mm in height. The inner wall is coated with petroleum jelly, and one end is wrapped with a breathable and impermeable membrane.

[0040] 3 Prepare the sample: Mix the weighed dry soil, cement, quicklime, fly ash, and aluminum powder, stir well, then pour in the acrylamide and ammonium persulfate dissolved in water, and stir well. Finally, the slurry is poured into the mold, and the delivery height is 60mm.

[0041] 4 Maintenance: Seal the mold and press the counterweight to maintain ...

Embodiment 2

[0043] Same as Example 1, the only difference lies in the content of dry soil and aluminum powder in the raw material: Weigh dry soil (alkali slag ratio soil 60:40), weigh 0.9% aluminum powder based on dry soil weight.

Abstract

The invention relates to a soda residue light stabilized soil, which is prepared from the following raw materials: dry soil, water, a curing agent and a foaming agent, and is characterized in that based on the weight of the dry soil, the dry soil is prepared from soda residue and soil according to a mass ratio of (40 to 60) to (70 to 30); the curing agent is prepared from 11-19% of cement, 4-10% of quicklime, 8-12% of fly ash, and 0.3-0.7% of acrylamide and ammonium persulfate, and the ammonium persulfate is 0.2-0.4% of the amount of acrylamide. The foaming agent may be aluminum powder, and the aluminum powder content is 0.9-1.1% by weight of the dry soil. The invention also provides a method for preparing the light cured soil.

Description

technical field [0001] The invention relates to the fields of concrete and environmental protection, and further relates to an alkali slag-solidified soil and a preparation method thereof. Background technique [0002] The ammonia-soda method is widely used in my country. Nearly 60% of the soda ash in my country is produced by the ammonia-soda method, which leads to the generation of a large amount of alkali slag waste. As the largest company producing soda ash in Tianjin, Tianjin Soda Factory was founded early and has a large production scale, which discharges a large amount of soda slag every year. Under normal circumstances, the alkali slag is treated by accumulating on the surface, and a large amount of alkali slag is deposited to form a "white sea", causing pollution to the surrounding sea area. The dry powder on the surface of the alkali slag is blown by the wind, causing air dust pollution, serious The environmental quality of the surrounding area has been affected. ...
