Fly Ash is a waste material produced from burning coal. Fly ash is abundant and often has to be disposed of in landfills or stockpiled. Ideally, this material should be consumed and transformed for another purpose. One option for consumption is to use the material to form concrete. Currently, ASTM International, whom is responsible for issuing and maintaining standardized methods and practices, recognizes fly ash as an acceptable additive in concrete. OSHA has also recognized fly ash use in concrete as a safe choice for the consumption of fly ash.
