Abstract: 
In this study, the performance of fiber reinforced cement mortar under elevated temperatures was investigated. Ninety prism specimens comprising one control group, three groups strengthened with discrete steel fibers and two groups strengthened with polypropylene fibers, were fabricated. The specimens were subjected to elevated temperatures of up to 1010°C in a furnace before they were tested to failure under four-point bending. According to the test results, the ultimate strength of the specimens generally decreased with an increase in the maximum imposed temperature. Steel fiber reinforced cement mortar performed better than polypropylene fiber reinforced cement mortar in terms of peak strength and post-peak behavior, when subjected to the same elevated temperature.
