Description
Summary:Black cotton soil is present on over 52 million hectares of land in India. Such a soil is incredibly hard when in dry state, except when wet, it becomes weak. Geotechnical engineers who work with expansive soils face a variety of challenges. Soil stabilization, which is frequently employed in foundation and road pavement construction, is one of the most crucial elements in the construction of a building. Stabilization boosts the engineering features of the soil, such as strength, and durability. In the current study, thermal waste is used as a stabilizing material to stabilize the locally accessible clayey soil. Fly ash was used to stabilize expansive soil in various concentrations, including 5%, 10%, 15%, 20%, 25%, and 30%. Fly ash possesses no plastic characteristic, the plasticity index (P.I.) of fly ash mixtures decreases as the fly ash content increases. As the doses of fly ash grows, the compaction characteristics, UCS and CBR values of stabilized soil increase up to specific percentages.
