Thermal Imaging as a Non Destructive Testing Implemented in Heritage Conservation

Abstract

The aim of this work is analyzethe relevance of Non Destructive Technique (NDT) thermal infrared imaging (TIRI) as a way of reference to the heritage conservation.The assessment of thermography testing was done in order to evaluate the correspondence concerning the physical and chemical characterization and compatibility among original and restored plastered mortars and stuccos, considering the correlation betweenthermal emissivity values and other well-known materials characterization methods such as Fourier Transform Infrared (FTIR), X-ray diffraction (XRD) and Modulated Differential Scanning Calorimetry (MDSC) whichconclusively evidenced the appropriate assimilationof plasters and stuccosapplied inheritage conservation.
