Non-destructive investigation techniques are largely used because of the outstanding advantages that they are capable of providing in a variety of applications. NOT methods, such as fibre optics microscopy, infrared thennography, ultrasonics and digital image processing, are applied in the laboratory of Materials Science & Engineering (Chemical Engineering Department), in the National Technical University of Athens (NTUA), on advanced and historic materials regarding arcliitectural surfaces and historic masonries, for research purposes such as: U materials quality control, as well as for technology assessment regarding the production of advanced materials(1) □ environmental impact assessment - materials and weathering mapping(2). □ evaluation of conservation materials compatibility and conservation interventions effectiveness on the scale of architectural surfaces and historic masonries[3,4,5,6]. □ strategic planning for the conservation interventions[7,8,9]. □ environmental management for the protection of cultural heritage(10,11) It is found that the combined use of the applied nondestructive techniques can allocate information concerning mechanical properties, microstructitral characteristics, energy and mass transfer phenomena such as humidity capillary rise and evaporation, and so on. In addition, the application of these techniques can give precise interpretation of the actual physico-chemical phenomena, when combined to laboratory application investigation of critical parameters. A Geographic Information System (GIS) is used on the scale of large historic complexes, in order to manage a multidisciplinary database, including environmental, architectural, structural and materials data. |
