Abstract : This paper presents the results of experimental investigations into the heating effect normal strength concrete (NSC) and normal strength fibrous concrete (NSFC). The physical changes and compressive strength of NSC concrete with and without steel fibers at room and at elevated temperature have been investigated. Cubes and cylinders have been cast and the unstressed residual strength test has been carried out to evaluate the compressive strength of all concrete mixes. The effect of temperature up to 800°C on compressive strength of concrete mixes and its comparison with that of the control specimens at room temperature at the end of 28 days has been investigated. The results show that at elevated temperatures, compressive strength of NSC was lower than that of NSFC. NSC and NSFC specimens were completely melted at 600°C and 800°C respectively.
