The engineering qualities of soil, such as its carrying capacity, shrink-swell characteristic, and shear strength, can be improved via soil stabilization. Because it reduces the difficulties involved in disposing of various types of industrial waste, using materials made from industrial waste to repair problematic soils is both cost-effective and environmentally friendly. This study’s main objective is to improve the soil’s engineering properties by replacing cement with ground-granulated-blast furnace slag (GGBS). Atterberg’s limits, compaction behavior, specific gravity, CBR, and UCS test findings are all examined in the current study using lime-GGBS. The agglomeration and flocculation of soil particles are caused by cation exchange, which is the method by which lime is used as a stabilizing element. The addition of lime-GGBS was done in this investigation at percentages of 0, 3, 6, 9, 12, and 15%. When compared to all other combinations, the optimum GGBS (15%) was shown to provide an increase in CBR and UCS values.

摘要

The engineering qualities of soil, such as its carrying capacity, shrink-swell characteristic, and shear strength, can be improved via soil stabilization. Because it reduces the difficulties involved in disposing of various types of industrial waste, using materials made from industrial waste to repair problematic soils is both cost-effective and environmentally friendly. This study’s main objective is to improve the soil’s engineering properties by replacing cement with ground-granulated-blast furnace slag (GGBS). Atterberg’s limits, compaction behavior, specific gravity, CBR, and UCS test findings are all examined in the current study using lime-GGBS. The agglomeration and flocculation of soil particles are caused by cation exchange, which is the method by which lime is used as a stabilizing element. The addition of lime-GGBS was done in this investigation at percentages of 0, 3, 6, 9, 12, and 15%. When compared to all other combinations, the optimum GGBS (15%) was shown to provide an increase in CBR and UCS values.
