fly ash are expected to be generated in the country by the year 2012. The Ministry of Power, Govt. of India estimates that 1800 million tonnes of coal use every year leading to generation of 600 million tonnes of fly ash by 2031-2032. Not only does this huge amount of fly ash create environmental problems it also eats up large tracts of land required for dumping of this waste. Since fly ash is
