This method was used to test a model of the concrete wall with the material inclusions with significantly different thermal properties. The study performed in climatic chambers consisted of heating the model wall with a 7.2 kW heat pulse, and then recording the thermograms during wall cooling, at regular intervals, using a thermal imaging camera. Based on the recorded temperature distribution on the thermograms the thermal properties and location of subsurface defects were concluded.}, doi = {10.4467/2353737XCT.14.252.3340}, url = {https://ejournals.eu/czasopismo/czasopismo-techniczne/artykul/the-use-of-active-thermography-to-detect-material-inclusions-in-the-walls} }
