Title: Performance of High-Volume Fly Ash Concrete in Hot Weather

Abstract: Thermal cracking is a serious problem with modern portland-cement concrete structures, especially cast-in-place massive elements made with relatively high cement content and cured under hot-weather conditions. From theoretical considerations and field experience it is concluded that blended portland-cement concrete mixtures containing 50 percent or more ASTM Class F fly ash by mass of the total cementitious material perform much better under these conditions.
