UK researchers are working to characterize the country’s abundant landfilled fly ash supplies to help ensure the material’s continued availability amid the planned closure of all UK coal plants by 2025.
Rice University engineers have developed a composite binder made primarily of fly ash that can wholly replace portland cement in concrete to make the end product both high-strength and more environmentally friendly.
Montana State University researchers are using fly ash to develop a more affordable ultra-high performance concrete that could help reduce maintenance costs on the state’s bridges and roadway infrastructure.
Engineers have developed a high-density polyethylene plastic incorporating fly ash that can be used to 3D print syntactic foam components, extremely strong and lightweight parts used in vehicles, airplanes, and ships.
Fifty-six percent of the coal ash produced in the U.S. in 2016 was recycled—establishing a new record and marking the second consecutive year that more than half of the coal ash produced was beneficially used rather than disposed.
