EFFECT OF LIME AND STONE DUST IN THE GEOTECHNICAL PROPERTIES OF BLACK COTTON SOIL

In the present study Black Cotton Soil was stabilized with a mixture of lime and Stone Dust. First an optimum value of lime was determined on the basis of some geotechnical properties of mixture of lime and Black Cotton Soil. Then Stone Dust was mixed upto 25% by weight with an increment of 5% in the optimized mixture of lime-Black Cotton Soil. California bearing ratio, unconfined compression strength and maximum dry density values were determined of these modified mixes. Morphology of the soil and admixture has been studied by Scanning electron microscope (SEM), while mineralogical composition has been determined by X-Ray diffraction technique (XRD).
