This research examines the influence of Ground Granulated Blast Furnace Slag (GGBS) on soil properties based on a comprehensive experimental investigation. Soil specimens containing different percentages of GGBS (0%, 5%, 10%, 15%, 20%, and 25%) were evaluated for compaction, Atterberg limits, specific gravity, unconfined compressive strength, and California Bearing Ratio (CBR). Results show that GGBS can significantly influence soil properties. Specific gravity first increases and then becomes constant with increasing GGBS. Liquid limit and plasticity index reduce regularly, enhancing soil grading and minimizing plastic behavior. Optimum moisture content reduces first and varies, while the maximum dry density rises first and experiences regular change. Unconfined compressive strength reduces first but enhances with greater GGBS content. CBR of soaked and unsoaked samples experiences intricate regular change. Sieve analysis experiences enhanced soil grading with increased GGBS. The research concludes that GGBS is a good soil stabilizer but its performance depends on the percentage added and exact requirements of the application.
