A Review of Soil Improvement in Problematic Black Cotton Soil by Using Dry Kota Stone Slurry and Fly Ash

Abstract

Black Cotton Soil (BCS) is particularly rapid-expanding and swelling when it meets water. This trait of soil results in extremely low soil strength and other attributes. Soil stabilization by various stabilizers is required to enhance its characteristics. Stabilization is a technique used to improve the soil's structural integrity. Soil stabilization raises the subgrade's load-bearing capacity, allowing it to better support the pavement and foundation. It is accomplished by increasing the soil's shear strength and regulating its shrink-swell qualities. Expansive soils could have their engineering qualities enhanced via several different means. The problematic soils are either excavated and replaced with excellent, higher-quality material or treated with an additive. This paper analyzes soil improvement in problematic BCS using dry Kota Stone Slurry (KSS) and Fly Ash (FA). In thermal power plants, FA is produced as a byproduct of burning coal. It's made up of dust and ash that are swept up in the exhaust when fuel is burned. The findings highlight its potential to address soil-related issues, enhance agricultural productivity, and contribute to sustainable land utilization practices.
