Declining Supply of Fly Ash. Fly ash is a by-product of burning pulverized coal in power-generating plants. During combustion, mineral impurities in the coal (clay, feldspar, quartz, and shale) fuse in suspension.The fused material cools and solidifies into spherical glassy particles called fly ash that are carried away from the burning zone in the boiler by the flue gases, and then collected ...

Fly ash can be processed by screening or air classification to improve its fineness and reactivity. Some non-concrete applications, such as structural fills are not affected by fly ash fineness. However, other applications such as asphalt filler, are greatly dependent on the fly ash fineness and its particle size distribution.

Fly ash, also known as flue ash, is a green material that originates from one of the earth's largest sources of air pollution—coal. More than 50 percent of electricity in the U.S. comes from coal-fired power plants. 2 Because these plants are so widely used, fly ash is one of the most abundant industrial by-products on Earth.

Fly ash is a coal combustion product.It is part of a set of products that makes up the most abundant waste materials worldwide. If not collected, this waste material is blown out with the flue gas in a coal fired power plant.Fly ash exists after combustion because ash adheres to coal, making up between 1-15% of its weight. About 90% of the ash is fly ash, while 10% is bottom ash.
