Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash.
Fly ash is used in the production of Portland Pozzolana Cement (PPC) in three different ways (1) as a raw material along with limestone in the cement kiln, (2) grinding of fly ash and cement in the mill and (3) blending of Ordinary Portland Cement (OPC) with fine fly ash (Bhattacharjee & Kandpal, 2002).
Fly Ash is considered to be a byproduct from burning pulverized coal in electric power generating plants. The Fly Ash is a kind of artificial pozzolan, particularly designed and processed to attain maximum performance on most of the cement and concrete applications. In the course of producing high quality Industrial Fly Ash
