      generally, concrete structures have a high fire resistance. after fire, it is of economic interest to reuse thestructure after appropriate repair based on a reliable assessment of the residual strength. this paperpresents an experimental study on the performance of self-compacting concrete (scc) subjected to hightemperature. six scc mixtures with different cement grade were made and the specimens of eachconcrete mixture were heated up to 5 various temperatures (27c°, 100c°, 200c°, 300c°, 400c°). in orderto ensure a uniform temperature throughout the specimens, the temperature was held constant at themaximum value for 1 h before cooling. upon finishing this work, important results on the effect of hightemperatures on compressive strength of self-compacting concrete (scc) were obtained, thus providing amajor contribution for the recovery design of structures that had been subject to fire.
