Identificazione di anomalie nella stratigrafia di intonaci storici mediante termografia IR

The authors present the results of infrared (IR) thermography tests carried out on a masonry specimen representative of an historic building with lime-based plaster, which presents artificial anomalies, e.g., lack of adhesion among the layers of plaster and inclusions of various materials. The procedures here applied show the conditions for observing possible defects on a building element with such as non-invasive technique. It provides a fundamental support to the development of an in-depth knowledge of historical structures and allows setting the necessary interventions to ensure a constant care to the built heritage.
