Thermal power stations using pulverised coal as a fuel generate large quantities of fly ash as a by product. Fly ash poses serious environmental problems as regards to its safe disposal. Physical and chemical properties of fly ash need to be considered prior to evaluation of possible utilisation of fly ash in various fields such as backfilling of opencast mines, reclamation of waste lands and used in construction industry. The physical parameters investigated were Bulk Density (BD), Moisture Content (MC), Specific Gravity (SG), Water Holding Capacity (WHC), Liquid limit, Plastic limit, Grain Size Distribution (GSD) and Permeability. These physical properties of fly ash are of great importance in backfilling of opencast mines and reclamation of waste land.
