Curing agents cause a chemical reaction that changes a material from a liquid, gel-like or flowable state to a hard, durable solid. This change is at the heart of soil stabilization technology.
1. Principle of action
This chemical reaction is usually carried out through polymerization reaction, cross-linking reaction or polycondensation reaction, etc., thereby forming a polymer or network structure and increasing the intermolecular binding force of substances. In soil solidification, the solidification agent undergoes physical and chemical reactions with soil particles and water in the soil to change the microstructure of the soil.
2. Main functions
- Promote curing reaction: The active ingredients in the curing agent (such as amines, acids, phenols or specific inorganic ions) react with the main material to form a cross-linked structure.
- Improve material performance: 3. Practical application significance
- Change material properties: 3. Practical application significance
3. Practical application significance
In engineering practice, such as road base construction, adding curing agent can make the originally loose soil slab into a whole, and its strength will increase with time, eventually achieving an effect similar to concrete, but with lower cost and easier construction.
