A Factsheet from Austin Energy's Green Building Program: Fly Ash
Fly ash, a by-product created by burning coal, can be used as a supplement to, and a partial replacement of, portland cement in concrete. On average, 30 percent of the fly ash produced in the United States is recycled into concrete mixes thereby reducing disposal requirements. Reduction of energy costs and pollution resulting from the production of portland cement is an added benefit of using fly ash.
