    Fly ash is perhaps the best known type of coal ash. It is a powdery material made up of tiny, separate glass spheres. Chemically, fly ash consists primarily of silicon, aluminum, iron and calcium oxides. The most common application for AEP fly ash is as partial replacement for cement in concrete, concrete products and grouting applications.
