This research work presents the efficacy of sodium based alkaline activators and flies ash as an additive in improving the engineering characteristics of Black cotton soils. Sodium hydroxide concentration of 2 molal is used as activator. The black cotton soil behavior was studied in addition of different percentage of fly ash such as 5%, 10%, 15%, 20%, 25% & 30%. The activator with fly ash percentages of 5%, 10%, 15%, 20%, 25% and 30% relatively to the total solids. The Atterberg limits, specific gravity, unconfined compressive strength and Standard Proctor’s compaction tests were performed on expansive clay soil. The results are indicated that in addition of fly ash with Alkali Activator solution with different concentrations reduces the liquid limit and plasticity index and increases the plastic limit of the Black Cotton soil. The optimum moisture content (OMC) and maximum dry density (MDD) curves indicate that addition of fly ash with Alkali Activator solution with different concentration increases the OMC but decreases the maximum dry density of the Black Cotton Soil. Increase in the Unconfined Compression Strenght was observed with increase in the percentage of Fly Ash. With increase in the percentage of fly ash with increasing concentration of Alkali Activator, unconfined compression strength was increased with the curing period.
