According to the principle of infrared radiation, the infrared thermal imaging technique was applied to study the fire damage of concrete. The average temperature rise of infrared thermal images on the surfaces of concrete specimens heated up to 900°C was continuously monitored for five minutes. There existed linear relationships of the average temperature rise with the fire temperature and the relative residual concrete strength above 200°C. When the temperature was below 200°C, the damage of concrete was insignificant. The fire damage of concrete structures in situ was also assessed using this technique.
