In developing countries like Pakistan, Due to rapid growth and population, an increase in the production of industrial waste is rising significantly day by day. Stabilization of soil using those industrial wastes not only gives proper usage of waste materials but also increases the cost-benefit ratio as a whole. In this research work, an attempt was made to use Ground granulated blast furnace slag (GGBFS) in the stabilization of District Khairpur Mirs’ soil. Generally, while dealing with building construction industry such as foundations for buildings, highways such as subgrades as a foundation and in earthen dams as landfills sometimes there exist naturally occurring unsuitable soils. District Khairpur Mirs’ soil is accounted for the different laboratory tests and the concerned District Khairpur Mirs’ soil found to be relatively unsuitable; therefore, various percentages of ground granulated blast furnace slag were added to make it suitable. To improve the concerned soil different percentages of slag are used, and samples thus formed so for were tested in the laboratory for this research work. Various laboratorial tests like particle size distribution, Atterberg limits, Modified Proctor test, AASHTO soil classification, and CBR test were performed on controlled and stabilized soil samples. The aim of this research study was to examine the influence of ground granulated blast-furnace slag (GGBFS) on the index, Compaction and mechanical strength parameters of natural Khairpur Mirs’ soil. Finally, based on laboratorial tests, it was observed that stabilization of soil by GGBFS made favourable changes on the index, compaction and strength parameters of District Khairpur Mirs’ soil.
