The paper discusses various characteristics of fly ash and the possibility of its utilization in the various sectors. During the last decade, India saw about 70% increase in the production of fly ash but roughly 130% increase in the utilisation. About 60% of Indian demand of electricity is fulfilled by coal fired thermal power plant. Fly ash is micron-sized powder obtained by burning of coal.
At present 170 million tonnes of fly ash is produced in India annually. Environmental pollution by fly ash is a major concern all over the world. Not many people know the fact that the major factor of much talked air pollution in New Delhi is because of fly ash originating from the thermal power plants of Badarpur and Rajghat. As per the Court orders, now both the plants are shut down and consequently there should be reduction in the pollution. Disposal of large amount of fly ash is a serious matter to address.With the appropriate characterization, it can be used as substitute material in various sectors, conserving the resources like soil, sand. Many government agencies have been employed and regulatory framework has been devised for a compressive research and development of potential usage of fly ash.
