Abstract: In this paper, the results of a series of experiments are presented to show the temperature-dependent stress-strain relationship of high-strength concrete (HSC) when exposed to elevated temperatures. The effects of mineral additions and test conditions on the stress-strain behaviour are discussed. The result shows that addition of fly ash (FA) was effective in improving the residual properties (compressive strength and elastic modulus) of concrete. All the concrete mixes had higher residual mechanical properties in the stressed tests than in the unstressed tests. In the stressed test condition, all the concrete mixes retained elastic modulus values close to the original unheated values.
