This study focus on the compressive properties of Steel Fiber Reinforced Concrete after being exposed to temperature between 20 and 800 °C. The effect of elevated temperatures on the compressive strength and elastic modulus (stiffness) of concrete are presented. High Strength Concrete (HSC) samples for this study were prepared with and without steel fibers. The volume dosage of steel fibers is 0.5 % out of total volume of concrete. The results indicate that the compressive strength and elastic modulus of HSC is increasing at the early phase but then decreasing with the increasing temperature, and the loss of elastic modulus is quicker than the compressive strength. Based on experimental result, the HSC mixes retained about 45 % of their compressive strength, on average, after exposure to 600 °C, and this was further reduced to only 8.7 % of High Strength Concrete C50-with steel fiber (HSCWF50SF) and 20 % of High Strength Concrete C50-without steel fiber (HSCNF50SF). |
