India is a major consumer of coal in India and will continue to remain so far many years to come. Combustion of coal in thermal power plant not only produces steam to run electricity generating turbine but also produces a large quantity of by-products like fly ash etc. About 80 thermal power plants in India are sources of fly ash, where around millions of tonnes of coal are used annually. India currently generates 100 million tons of fly ash every year. This produces 30- 40 million tonnes of fly ash unused every year. This disposal will need thousands hectares of storage land, which may cause further ecological imbalance. In fact, this waste material is simply disposed of in the form aqueous slurry on the adjoining areas. This type of disposal not only converts useful agricultural land to waste ones but also possesses a threat to the quality of environment. The human development of united nation development programme indicates that annually 83-163 million hectares of land is eroded in India causing productivity loss of about 4 to 6.3% of the total agricultural output worth $2.4 billion. Therefore, using fly ash as a building material has assumed great significance like never before. Several investigations have been carried out throughout the world to make an attempt to use fly ash in many civil engineering projects by virtue of its good properties as an ingredient of concrete.
