THE COMPRESSIVE STRENGTH OF FIBER REINFORCED CONCRETE (FRC) AT HIGH ELEVATED TEMPERATURES

This paper investigates the effect of fiber on the compressive strength of (FRC) at high elevated temperatures. Effects of key variables such as fiber content, several high temperatures and fiber type were studied. An experimental program was conducted to achieve the required objectives. 84 Cubes were tested under axial compressive loads. They were divided as follows. 12 Cubes without fibers as a reference, 72 Cubes were cast to study the effect of fiber content and fiber type at several high temperatures. It was found that the content and type of fiber have approximately not effect on improving the behavior of (FRC) at high elevated temperatures.
