STUDY OF THE SETTLING CHARACTERISTICS OF FLY ASH
2011-5-16 · Fly ash is a very fine material which is produced by burning of pulverized coal in boilers of thermal power plants. Worldwide more than 65 of fly ash produced from coal power stations is disposed off in landfills and ash ponds. The fly ash is sent to ash ponds in the form of slurry with water since it is economical.
