Application of quantitative impulse thermography for structural evaluation in civil engineering – Comparison of experimental results and numerical simulations

Abstract

The cooling-down process of building structures after heating-up with an external radiation source was analysed to detect voids inside and below the surface. Here, the results of a concrete test specimen containing voids with different sizes at various depths will be presented. These experimental investigations were compared to the results of simulations performed with a Finite Difference program.
