A Study of Black Cotton Soil and its Stabilization by Use of Lime and Sawdust

With rapid growth of population, fast urbanization and more construction of highway, buildings and other structures has resulted in reduction of good quality available land. The mechanical behavior of such nature of soil has to be improved by employing stabilization of Black Cotton Soil (BC soil) is studied by using Lime and Sawdust. Black Cotton soils are highly clayey soils (Montmorillonite clay mineral). The moisture changes in Black Cotton soils, compressibility and plasticity nature can be greatly improved with the addition of Lime and Sawdust. 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 Sawdust (% 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 Sawdust increases the California Bearing Ratio values i.e. the strength of soil to a great extent.
