Fly ash is an industry development and also freely available so we intend to apply it. This paper deals with the experimental have a look at on development of homes of expansive soil via fly ash replacement. Soil pattern used on this task is an expansive soil that is collected from Bachupally, By engaging in diverse assessments like plastic restriction, liquid limit, free swell index, unconfined compressive test (UCC) and California bearing ratio (CBR) we came to know that the soil sample is weak in shear, bearing and plasticity hence we repeated those experiments by replacing the soil sample with fly ash in various percentages like 10%, 20%, 30% and 40% and came to know that the soil properties are improved at 30% replacement like max dry density increased by 5.5%,plasticity index decreased by 25.4% and CBR value increased by 200%.
