Preservation, Safeguard and Valorization of Masonry Decorations in the Architectural Historical Heritage of Piedmont (Italy)

摘要

In the present paper, a project for integrated investigation is described, using noninvasive methods, specially designed for dealing with the highly diversified historic heritage of Piedmont (Italy). The stability of the decorated surfaces will be investigated by innovative Acoustic Emission (AE) and ultrasonic methods already experimentally tested in the field of artistic and monumental cultural heritage in Italy. The ultrasonic investigation techniques allow assessing separations, defects and damage phenomena that can regard the decorated surfaces and the masonry supports. Innovative acoustic methods will allow distinguishing a well-preserved artwork in comparison to a damaged one providing a quantitative criterion for the definition of intervention priority.
