Application of IRT for NDT of Concrete Structures
The objective of condition assessment of existing reinforced concrete structures is to provide insight into current condition of the observed structure, to predict development of deterioration, and to assess the influence of defects found on the safety and life expectancy of the structure. NDT using IR thermography generally consists of thermal stimulation of the object under examination and monitoring of its surface temperature variation during the transient heating or cooling phase. The existence of inhomogeneities in the core material affects the heat transfer and thus causes local changes of temperature distribution on the surface of the observed structure, which is then recorded using an IR camera. In this paper, the use of active IR thermography technique for detecting defects in reinforced concrete structures will be presented. Possible use of active thermography with post processing techniques that can be applied for detecting the defects in near surface region of reinforced concrete structures will also be presented. Step heating (SH) thermography, pulsed phase (PPT) thermography, principle component thermography (PCT) and correlation operators’ technique were used in the post-processing of thermogram sequences in order to determine the existence of defects in concrete samples.
