Two hundred thirty-one creep strain tests were conducted at temperatures from ambient to 1200F over periods from 6 to 24 hours on 2X4-in. cylindrical concrete specimens. In addition, forty-five compressive strength tests were conducted on heated concrete specimens. Test variables included load (0.30, 0.45, and 0.60 (f' sub c)), temperature (73 to 1200F), rate of heating (0 and 10F/min.), length of heating (6 and 24 hr), aggregate type (calcareous, siliceous, and lightweight), variation of compressive strength with temperature, and concrete relative humidity (0, 50, and 100% RH). A model of short-term creep of concrete at elevated temperatures as a function of significant test variables was developed.
