Conclusions are drawn con­cerning the proper exploitation of the laboratory results in field applications in the frame of on-going restoration projects of ancient stone monuments. The need of continuous bidirectional interaction between the scientific per­son­­nel working in the site and the scientists working in the laboratory is empha­sized. The role of the Digital Image Correlation technique in quantifying para­sitic effects influencing the laboratory data is proven decisive. The need to use modern sensing techniques, providing data from the interior of loaded res­tored complexes (simulating restored structural el­ements), like the Pressure Stimu­lated Currents and the Acoustic Emissions ones, according to a com­bined manner is highlighted. The capability of these two techniques to monitor the damage evolution within the mass of the elements tested and to provide clear pre-failure indicators renders them flexible tools in the hands of engineers designing the restoration projects.</p> ER -
