The effects of the temperature in which high strength concrete with fly ash is mixed, placed and cured is examined in this paper. A comprehensive experimental study was conducted to determine the compressive strength development of high strength concrete mixtures with fly ash (Class C and Class F) when subjected to different hot and cold weather mixing and curing regimes. Strength development and stress strain curves are plotted to reflect the data. These results are compared with data collected from specimens cured under standard laboratory conditions according to ASTM specifications. Conclusions are made regarding the effect temperature and fly ash replacement level have on the strength development of high strength concrete made with Class C or Class F fly ash.
