Abstract. Fly ash (FA) is the principal industrial waste byproduct from the burning of solid fuels. FA is a powdery solid that is constituted mostly of unburned carbon (UC), metal oxides (Si, Fe, Ca, and Al), and other inorganic substances. UC is an inexpensive source of activated carbon that plays an important role in FA adsorption …

One of the reasons fly ash is so popular as an additive, of course, is that there's a lot of it left behind by coal plants. At the same time, one big point in favor of fly ash's use in concrete and brick is the idea that a chemical reaction is believed to effectively trap any minute levels of fly ash pollutants within the building material.
