Abstract:

Fly ash is produced as a result of the combustion of coal in coal-based thermal power plants. In the present work physical, chemical and leaching properties of fly ash have been investigated. Fly ash particles are generally in spherical shape. They consist mostly of silicon dioxide (SiO2), aluminum oxide (Al2O3) and iron oxide (Fe2O3). Fly ash like soil contains trace concentrations of the following heavy metals: nickel, chromium, iron, zinc and lead. The leaching test result shows that the concentration of heavy metals element nickel, chromium and zinc is within the permissible limits of Indian standard (IS 10500; 2004) while elements concentrations of lead and iron have crossed the standard limits. These may cause the many harmful effects on the human health.
