The results of the laboratory studies undertaken to investigate the effect of PhosphoGypsum (PG) with Fly Ash (FA) on geotechnical properties of clayey soils for soil stabilization purpose are being presented in this paper. The test results on clayey soil treated with different dosages of stabilizer shows that the increase in PG with FA content increases the volume stability as well as the strength of the soil. Observations are made for the changes in the properties of the soils such as Unconfined compressive strength (UCS) test and microstuctural analysis using SEM and EDS results. The study on feasibility of PG and FA for increasing the strength and microstructural development of clayey soils is being carried out thereby proposing an effective solution for the conventional problem of waste management.
