Application of infrared thermography and geophysics to the architectural field

The scope of the present study is a multimethodological approach to nondestructive evaluation of architectural structures. Three different techniques, such as infrared thermography, ultrasonics and geoelectrics are analysed. Indeed, a synergic use of the different methods may help for estimation of buildings degradation sources. The investigation is carried out in laboratory by considering specimens, which include both masonry blocks or two-components structures such as plaster over a support of marble, brick, or tuff. Air bubbles are intentionally created inside specimens to simulate detachments and/or cracks. Examples of in-situ applications are also reported. In particular, the geoelectric methods are used for the comprehension of underground fluid circulation, while infrared thermography is used for the inspection of the status of tiles covering the walls of a building.
