Uses, Benefits, and Drawbacks of Fly Ash in Construction

 · Fly ash is a fine powder that is a byproduct of burning pulverized coal in electric generation power plants. Fly ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement.

Pulverized Fuel Ash

Fly ash. Pulverized fuel ash is formed during the process of combustion of pulverised coal in the furnace of the power station''s boiler. The coal is ground to powder-coal in coal mills, before being blown by compressed air into the furnace and burned at temperatures ranging between 1300 and 1600 °C, depending on the type of boiler in question.
