Continuous expansion in road networks of India and for smooth movement of traffic, it is obvious that the MSE walls would be constructed all over the country in upcoming years. These structures requires huge amount of inert, non-cohesive and granular materials like sand for backfilling, but in future, sand is not going to be available in such quantities. Therefore it becomes our responsibility to search for some locally available waste materials to be used in place of sand in MSE walls. In this study, one of the type of coal ash generated from the thermal power plants i.e. pond ash - a non-cohesive material, coarser in size and available in huge quantities, is analyzed to be used as partial replacement of conventional backfill materials. Badarpur sand was used to be mixed in different proportions with the pond ash to control the variation in physical properties of pond ash. Pullout tests performed with 20%, 25% and 30% incorporation of Badarpur sand with the pond ash shows an increases in the pullout resistance by 6.76%, 12.03%, and 18.04% respectively. The physical properties of Pond ash were found suitable to be used as backfill material in MSE walls and other retaining structures.
