Creep, Strength, and Elasticity of Concrete at Elevated Temperatures
Laboratory tests were conducted to determine drying effects on structural concrete exposed to elevated temperature conditions existing in a flash-evaporation water desalting plant. Creep, compressive strength, and modulus of elasticity were measured on concrete dried at temperatures of 73, 130, 180, 230 and 290 deg F over a period of 6 mo. Results show creep at 290 deg F is about 5 times the creep at 73 deg F. Compressive strength is lowest at 180 deg F. Elastic modulus is lowest at 230 deg F and about one-half the modulus at 73 deg F. The variations in concrete properties indicate that possible changes in the composition of concrete occur at temperatures above 180 deg F. The report includes data on strength and moduli changes during storage, strain of unloaded concrete specimens, and weight loss at the different temperatures. (Author)
