Soil solidifying agent with high water-resistance and application thereof

Abstract

The invention discloses a soil solidifying agent with high water-resistance. The soil solidifying agent is an emulsion and comprises a binder, a reinforcing agent, a dispersant and a filling material, wherein the binder is a high-molecular copolymer with a binding property, and the filling material is a nanometer alumina particle. The soil solidifying agent provided by the invention has strong flexural strength, impermeability, frost heaving resistance and frost boiling resistance, can effectively treat a soft base and enables a pavement base to have good integral stability, flexibility and elasticity.

Description

technical field [0001] The invention relates to a soil curing agent, in particular to a soil curing agent with high water resistance, belonging to the field of building chemistry. Background technique [0002] In the construction of buildings, bridges, roads, etc., it is often necessary to solidify the soil. The essence of soil solidification is to use external admixtures to physically and chemically treat the soil to change the composition and engineering properties of the soil, so as to improve the strength of the soil and improve the pressure of the soil. substantive purpose. [0003] At present, the commonly used soil curing agents in the construction industry are lime, cement, etc. for soil improvement. These curing agents have a good effect in the early stage of the project, but in the long-term soil curing project, people gradually realized that simply using traditional lime, There are obvious deficiencies in soil solidification materials such as cement, which cannot...

Problems solved by technology

[0003] At present, the commonly used soil curing agents in the construction industry are lime, cement, etc. for soil improvement. These curing agents have a good effect in the early stage of the project, but in the long-term soil curing project, people gradually realized that simply using traditional lime, There are obvious deficiencies in soil solidification materials such as cement, which cannot meet the development needs of engineering construction. Common problems include: insufficient compressive strength, so that the strength can only be compensated by increasing the amount of curing agent added during construction; insufficient water resistance Well, the foundation soil cannot be consolidated after prolonged soaking in rainwater

Specifically, lime can be used for shallow subgrades, but not for soft soil with high water content; cement can be used for soft soil reinforcement, but its adaptability to soil quality is poor and the cost is high
