Abstract: Expansive soils pose significant challenges in geotechnical engineering due to their tendency to swell and shrink with changes in moisture content, leading to detrimental effects on infrastructure stability. This study investigates the effect of incorporating Granulated Blast Furnace Slag (GBFS) on the compressibility behavior of expansive soils. A series of laboratory tests including compaction, swell, and consolidation tests were conducted on expansive soil samples mixed with varying percentages of GBFS. The results reveal that the addition of GBFS modifies the compressibility characteristics of expansive soil significantly. The optimum percentage of GBFS addition is identified based on the reduction in swell potential and compressibility parameters such as coefficient of compressibility and consolidation characteristics. The findings of this study provide valuable insights into utilizing GBFS as a sustainable and effective solution to mitigate the compressibility issues associated with expansive soils, thereby enhancing the performance and longevity of civil engineering structures built on such problematic soils. Further research could explore the long-term performance and environmental impacts of GBFS-treated expansive soils under various loading and environmental conditions.
