| Abstract: |
| According to infrared testing principle, infrared thermal image technique was applied to research the fired damage of concrete. The changes of average temperature rising of infrared thermal image of fired concrete with time was obtained, and the regressive equations of average temperature rising of infrared thermal image to the fired temperature and the loss of strength of ordinary cement concrete were established. |
| Key words: infrared thermal image,concrete,fired damage, |
