This study uses Ultrasonic Pulse Velocity (UPV) to assess the quality of SFRC after exposure to high temperatures. Prism specimens were cast without steel fibre content and with 1.5% steel fibre volume fractions. Following a 28 -day curing period, the concrete specimens were dried and then subjected to a heating regimen in an electric furnace. The temperature inside the furnace was gradually increased to reach four target levels: 100C, 300C, 500C, and 700C. Each temperature level was maintained for a duration of 1 hour. The exposed specimens were then cooled down to ambient air. At 700C, the quality of normal concrete significantly dropped to "Doubtful", while Steel Fibre Reinforced Concrete (SFRC) maintained a "Medium" quality. The Response Surface Methodology (RSM) model is proposed to predict the quality through the UPV at various elevated temperatures. The adjusted R squared value for UPV before and after temperature exposure was observed to be 0.9729 and 0.9407 respectively. This research explores how to optimize steel fibre-reinforced concrete (SFRC) for better performance at high temperatures. This is crucial for structures exposed to fire, such as tunnels, bridges, and high-rise buildings. Improved SFRC behaviour under high temperatures translates to enhanced safety and potentially extends the life of structures in fire scenarios.
