Fly Ash Topic - concrete.org
Fly ash is a by-product from the combustion of pulverized coal, and is widely used as an ingredient in hydraulic-cement concrete. Because it improves many desirable properties of concrete, it is introduced either as a separately batched material or as a component of blended cement. Fly ash reacts with the hydrating hydraulic cement to form a cementing medium.
