Abstract

Thermographic approaches, passive and active, are widely used due to the outstanding advantages that they offer in a number of applications and particularly for the assessment of materials. Nonetheless, there are limitations; depending upon the approach used, as well as on the materials’ thermal, optical and physical properties, proper assessment (detection and/or quantification) is feasible. In this work, different applications employing thermographic testing, concerning the assessment of various building materials and historic structures, are presented. The following applications are included: determination of emissivity values (building and structural materials), study of moisture in porous materials, impact assessment on consolidated stone, evaluation of cleaning interventions on Pentelic marble and evaluation of the state of conservation of mosaics. Results presented show that thermography approaches can be used successfully for the structural integrity assessment of the tested materials and/or structures.
