Abstract
Testing of concrete quality of bonded steel reinforcement by the means of infrared thermal imager, study of sticky steel reinforcement concrete component under the irradiation of an external heat source surface temperature with time, spatial distribution and variation analysis internal hollowing defect thickness, size and thermal infrared imager vertical shooting angle and emission rate and other factors on the effect of infrared thermal imaging. The test results show that, the greater the thickness of internal defects, hollowing the greater area is easy to be detected. In the presence of internal defects, contrast the thickness of the site with no defect parts of the surface temperature, defect site temperature is significantly lower.
