Soil is the basic foundation for any civil engineering structures. It is required to bear the load without failure. In some places, soil may be weak which cannot resist the oncoming load. In such cases, soil stabilization is needed. Numerous methods are available in the literature for soil stabilization. But sometimes, some of the methods like chemical stabilization; lime stabilization etc. adversely affects the chemical composition of the soil. In this study fly ash and lime sludge were mixed with black cotton soil to investigate the relative strength gain in terms of CBR and compaction. The effect of fly ash and lime on the geotechnical characteristics of clay-fly ash and clay-lime mixtures was investigated by conducting standard proctor compaction tests were performed as per Indian standard specifications. The black cotton soil used for these experiments was brought from the site, near bamni. The physical properties of soil were determined as per IS specification. Fly ash was brought from the CSTPS chandrapur. Its finely divided residue resulting from the combustion of coal from electric generating plants. It has high water absorption capacity.
