Fire accident is a disastrous event which causes damage to life and property. When an accidental fire occurs, the duration of fire is less but the intensity of heat produced will be more. In addition to accidents, there are some special structures which are subjected to high temperatures for specific purposes like chimneys, rocket launching pads, etc., where the concrete is subjected to high temperatures. In these cases, the concrete used should be capable of resisting high temperatures. Steel fiber reinforced concrete is one such fire-resisting concrete. The present study aims at collecting literature related to steel fiber reinforced concrete when exposed to high temperatures. It also aims at investigating its performance when subjected to high temperatures and also its suitability as a fire-resisting concrete.
