India is a geographically diverse country with varied soil types in different places. As a result, stabilising techniques are employed to enhance those regions with low bearing capacity. Soil strength is improved using both mechanical and chemical stabilising techniques. In the mechanical approach, mechanical energy is employed (rollers, plate compactors, tempers, etc., depending on the choice or type of the soil) to enhance soil characteristics by compaction. Chemical Soil Stabilization is a chemical approach that involves blending and combining chemical additions to improve the soilâ€™s engineering qualities. Chemical substances such as calcium lignosulfonate, granite dust, cement, and fly ash were added in. Although calcium lignosulfonate may stabilise a wide variety of soil types, it works best in soft soils and clay soils with moderate to medium flexibility. Granite dust is primarily used in clay soils with a lot of flexibility.
