Abstract: : Expansive soil covers over 51.8 million hectares of land area in India (mainly Black Cotton soil). The basic trait of these expansive soils is that they are highly hard while dry but lose all of their strength when wet. Because of this attribute of expansive soils, these soils provide issues all around the world that geotechnical engineers must address. Soil stabilization, which is frequently utilised in foundation and road pavement constructions, is one of the most significant features for construction purposes; this is because such a stabilization regime increases engineering qualities of the soil, such as volume stability, strength, and durability. The problematic soil is removed or replaced throughout this operation is completed;The current study attempts to stabilise black cotton soil from Shivnath River Pulgaon Durg Bhilai utilizing fly ash sourced from JayPee Cement Limited Bhilai . Expansive soils are stabilized using different quantities of this Mixture, such as 10%, 20%, 25% . Because fly ash has no plastic characteristic, the plasticity index (P.I.) of clay-fly ash mixtures decreases in value as the fly ash component increases. Finally, the addition of fly ash reduces the flexibility of the expanding soil while increasing its workability by modifying its grain size and colloidal response. 3 trials of different composition are prepared and tested.
