An Experimental Study on Stabilization of Expansive Soil using Admixture

The recent developments and application in the use of advanced composites in the improvement of soil are increasing on the basis of specific requirements and national needs. The need of efficient stabilization and strengthening techniques of existing soil has resulted in research and development of newer materials for improvement. Particularly for the black cotton soils which have high swelling and shrinkage tendencies, demands great deal of attention for stabilization. Modification of black cotton soils by admixtures is a common method for stabilizing the swell shrink tendency of expansive soils. Advantages of chemical stabilization are that they reduce the swell shrink tendency of the expansive soils and render the soils less plastic. As a further step towards the innovative materials to be used for the stabilization, this study endeavor to use waste material copper slag for the soil improvement. Copper slag, which is produced during production of copper from copper ore, contains minerals like iron, alumina, calcium oxide, silica, etc. For every tonne of metal production about 2.2 tonne of slag is generated. By using the admixture described above, Copper slag the index properties of soil has been improved. The various tests like Plasticity index, Standard Proctor and Swell index were performed and the result we got show much improvement. Soil has been collected from Umrakh region near SNPIT and RC College and the Admixture from SWIL JhagadiaCopper Limited , Gujarat. Priyank H. Patel | Ushma S. Thakor | Shaikh Heena H.
