“…Nevertheless, the general understanding is that the use of non-destructive prospecting techniques for highly heterogeneous materials is mostly helpful to assess existing masonry structures in a qualitative way [ Autiero et al ., 2021 ; Binda et al ., 2000 ; Schuller, 2003 ; Valluzzi et al ., 2018 ]. In this regard, the most common applications of NDT for the qualitative assessment of masonry structures are: (1) evaluation of the inner morphology and structural layout [ Luchin et al ., 2018 ; Riveiro et al ., 2013 ; Zielinska & Rucka, 2018 ]; (2) evaluation of the level of deterioration and damage [ Masini et al ., 2010 ; Ramos et al ., 2018 ]; (3) quality control and assessment of the efficiency of repair actions [ Binda et al ., 2013 ; Valluzzi et al ., 2018 ]; and (4) preliminary estimation of elastic mechanical properties [ Martini et al ., 2018 ; Miranda et al ., 2016 ; Van Eldere et al ., 2019 ].…”

Background: The conservation of the built masonry heritage requires a comprehensive understanding of its geometrical, structural, and material characteristics. Non-destructive techniques are a preferred approach to survey historical buildings, given the cultural value of their fabric. However, currently available techniques are typically operated manually, consuming much time at operational and processing level and thus hindering their use for the on-site inspection of heritage structures. Methods: A novel automated sonic tomography system was designed and built to inspect and obtain information about the inner structure and damage of historic masonry walls. The system consists of a hitting device mounted on a frame that can be placed adjacent to the wall under analysis. The hitting device can move along the surface within the frame area in X, Y and Z directions, generating the sonic wave. The receiving system is a scanning laser vibrometer, able to measure from the distance the displacement of a focused point over time, recording the wave when it reaches the opposite surface. Results: Six stone masonry walls with different interior geometries were constructed at the laboratory by a professional stonemason. The construction of the walls was carefully documented, including the generation of detailed photogrammetric models of each single stone. The system was applied to survey the six masonry walls. Since the inner morphology of the walls is known, the resulting tomographic images could be compared with the ground truth. Conclusions: Automating the inspection allowed to collect thousands of data in a few hours. New software was also developed to automate the processing of the data. Results are expected to highlight the potential of tomography to obtain quantitative information about the interior of heritage structures, while providing new tools that make the implementation of the technique more practical for professionals. Data, software and models have been made publicly available.

“…The primary goal is to validate the UST and the RHT as reliable tools for comprehending the mechanical attributes of the natural stone present in the Great Mosque. The former assesses elastic ultrasonic wave propagation velocity, while the latter reflects the stone's superficial strength through a rebound index, both of which can be potentially correlated with the stone's compressive properties [2].…”
