Soil is a base of structure, which really underpins the structure from underneath and disseminates the heap successfully. On the off chance that the dependability of the dirt isn't satisfactory, disappointment of structure happens in type of settlement, breaks and so on. Extensive Soils like Black cotton soils are progressively in charge of such circumstances and this is because of essence of montmorillonite mineral, which has capacity to experience substantial swelling and shrinkage. To defeat this issue, the properties of soil must be progressed. Soil Stabilization is compelling procedure that tends to this issue by adjusting the properties of soil. The present examination manages the adjustment of Black Cotton Soil utilizing Fly fiery remains and Iron Powder. The admixture i.e., Iron powder is mixed with unmodified soil in shifting rates to acquire the ideal level of admixture required for soil adjustment. The outcomes demonstrate that Maximum Dry Density and CBR esteems were enhanced after the expansion of fly fiery remains and Iron Powder to the dirt. In this comparative study laboratory tests such as Atterberg’s limits, Compaction tests and CBR tests were carried out under both soaked and un-soaked conditions, the CBR values of clay with fly ash and iron powder mixes were observed with different % such as 0, (9%+1%)=10, (18%+2%)=20, (27%+3%)=30, (36%+4%)=40, (45%+5%)=50 Analysis of the formerly found result exposes the potential of fly ash and iron powder as an additive that could be used for improving the engineering properties of expansive soils.
