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

Abstract

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).
