Abstract

The aim of this study is to evaluate the performance of reinforced cement concrete (RC) columns and steel fiber reinforced concrete (SFRC) columns subjected to temperatures 100, 200, 300, 400, 500, 600 and 700o C by Non-Destructive Test (NDT) methods. In order to achieve this, both RC and SFRC columns are cast and cured for 28 days. Later these columns are heated in an electrical furnace up to a temperature of 7000 C for different durations of 1 hour and 2 hours. In this study, Rebound hammer and Ultrasonic Pulse Velocity (UPV) tests have been conducted to study the effect of high temperature on the behaviour of columns. Based on the results of this study, it is concluded compressive strength obtained through Rebound hammer test of SFRC columns are more than those of RC columns up to 5000 C. Results of UPV tests show a decrease in pulse velocity value for columns heated beyond 4000 C.
