Abstract:
The use of low-calcium fly ash in massive concrete structures, such as dams, substantially reduces the temperature rise due to hydration. By controlling concrete temperatures, cracking is minimized and water tightness increased. Fly ash is also cheaper to use than cement, and has the added benefit of being a reusable waste material, making fly ash concrete environmentally beneficial.
