| Abstract: | Impulse-thermography is one of the best suited non-destructive testing methods for the detection of surface-near voids of concrete structures. Here, the influence of material properties varied by concrete age, pore content, aggregate type and reinforcement density was studied systematically. Numerical simulations allowing the differentiation of the influence of single material parameters were complementing the experimental results. |
