FLYASH

Fly ash generated during the combustion of coal for energy production is one of the industrial by-products and it is recognized as an environmental pollutant. Because of environmental problem of fly ash, a good deal of work and applications on the utilization of fly ash has been undertaken worldover. Fly ash properties results primarily from the type of coal burned, the type of combustion equipment used and the fly ash collection mechanism employed.


Utilization of fly ash as a resources has been studied for decades in many areas such as in valuable element extraction, in environmental engineering, in ceramic products, in agriculture, in paint and plastic industry, in building products (brick, cement, aggregate, concentrate). Still, the utilization amount is very low. A major factor preventing utilization is the difficulty of producing quality-controlled fly ash materials that can meet market specifications.
