Environmental Benefits of Fly Ash
According to the US Federal Highway Administration, Fly ash utilization has significant environmental benefits including:
(1) increasing the life of concrete roads and structures by improving concrete durability,
(2) net reduction in energy use and greenhouse gas and other adverse air emissions when fly ash is used to replace or displace manufactured cement,
