“Stabilization of Black Cotton Soil Using Admixtures”

Stabilization of Black Cotton Soil (BC soil) is studied by using Lime and Fly ash. BC soils are highly clayey soils (Montmorillonite clay mineral). The moisture changes in BC soils, compressibility and plasticity nature can be greatly improved with the addition of Lime and Fly ash. This paper includes the evaluation of soil properties like Optimum moisture content, dry density, and strength parameter (California Bearing ratio value). Different quantities of Lime and Fly ash (% by weight) are added to the BC soil and the experiments conducted on these soil mixes. The result shows that the use of Lime and Fly ash increases the California Bearing Ratio values i.e. the strength of soil to a great extent.
