A Brief Review on Soil Stabilization Techniques

Soil stabilization techniques play a crucial role in enhancing the engineering properties of soils, ensuring their suitability for various construction applications. This review paper synthesizes the findings from multiple studies on soil stabilization methods and their effectiveness in improving soil characteristics. A comprehensive comparison of different stabilization techniques, including traditional methods like cement and lime stabilization, as well as modern approaches utilizing materials such as fly ash, coal bottom ash, and ground granulated blast-furnace slag (GGBS), is presented. The review examines the impact of these techniques on soil strength, moisture content, and swelling behavior. Additionally, innovative approaches such as microbial-induced carbonate precipitation and chemical grouting with polymers are explored for their potential in soil stabilization. The paper also discusses the environmental implications and economic feasibility of various stabilization methods. Through a thorough analysis of the literature, this review aims to provide insights into the selection and application of soil stabilization techniques based on specific soil conditions and project requirements.
