An Overview of Chemical Soil Stabilization Methods

Weakness of soil in bearing capacity, lack of desirable mechanical properties, swelling properties, etc. These issues and methods required new tricks that were achieved with the evolution of engineering knowledge and the emergence of new technologies in the field of civil engineering. Different methods for soil improvement are selected according to the importance of the project, primary soil type, area of the area to be improved, local access to materials, equipment and specialized personnel, environmental factors, engineers' experiences, economic issues and time allowed to complete the project. To be. It should be noted that knowing the area and studying the types of soils that cause problems is also very necessary and important. In many cases, the soil at the construction site is not suitable for use. In this situation, this problem can be solved with appropriate solutions. One of these solutions is chemical stabilization of soil. Chemical stabilizers stabilize and strengthen soil by creating chemical reactions and altering the structure and bonding between soil particles. In this type of reaction, soil particles completely lose their nature and become a substance with new characteristics. In this article, first, in addition to getting acquainted with the types of problematic soils, the most important methods of soil stabilization and soil formation and various methods of chemical soil stabilization are examined.
