Soda residue light stabilized soil and preparation method thereof

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. ...
