Utilization of Industrial Waste for Stabilization of Dune Sand

Rajasthan is a state which covers 10.4% of India and its western part is almost covered by Sand Dunes, hills of Dune sand created by wind. When designing and constructing highways or more generally any super structures on dune sands type of soil, it is essential to make sure that the foundation soil is stable and provides good support to the applied loads. It can be achieved by stabilization of Dune sand by mechanical means changing its gradation economically. Lime, cement, bitumen, ceramic granules, etc. are used to stabilize the Dune Sand in earlier attempts. In the present work Iron Dust of passing 2.36mm size which is an industrial waste and which creates a problem for disposal is utilized. Iron Dust of size 2.36mm is mixed with Dune Sand by weight in varying percentages i.e. 5%, 7.5%, 10%, 12.5% and15%. California Bearing ratio, Standard Proctor, Permeability and Shear Strength Tests are conducted for each mix composition.
