“…The transmitters generate longitudinal, transversal waves, whose expansion depends on the mechanical properties of the material (Bodare, 2005). Material measurements of the ultrasonic pulse speed may be performed in three ways: directly, semi-directly and indirectly (Kahraman et al, 2008;Meola et al, 2005). For quality measurements, the surface of the measured material must be smooth so that transmitters and receivers have good contact.…”

The compactness of dimension stone blocks was previously controlled through various methods that were partially based on personal experiences, acoustic and visual observance of materials. With the development of technology, the ultrasonic pulse method is frequently used for the examination of stone test pieces and with an analysis of acquired data through the tomography method, the compactness is determined. The monolith stone blocks that are found at a site contain hidden discontinuities. The technique of data acquisition and the use of various instruments enable a good overview of the block interior. With an increased number of measurements, a suitable classification is prepared that helps reduce modification costs and increases the quality of stone blocks. The control methodology of compactness is based on the passage of longitudinal waves through the stone block without damaging the block during control. High differences in speed show irregularities in the material. With the observation system, we can prepare a tomography of the measured profiles that show us the locations of irregularities that should be observed more closely. During in situ measurements, the data for comparison with measured results are acquired. Determination of critical locations is of extreme importance before the processing of the block into smaller stone products or during the reconstruction of older stone elements or sculptures. The purpose of "in situ" measurements is to prepare a simple and fast method for the evaluation of materials compactness and for production work.

“…That knowledge could be achieved on a quantitative basis by establishing a technique for the in situ thermal monitoring of structural cracks varying in depth. Being supportive to that QIRT examination, the depth of the structural cracks can be estimated on a quantitative basis by the UPV measurement taken on site in the indirect transmission mode [11,12].…”

The key concern of the study was the in situ assessment of cracks in historic masonry structures by quantitative IR thermography (QIRT). To better understand the potentials and/or limits of QIRT for that purpose, the non-destructive in situ survey composed of QIRT and ultrasonic testing was conducted on a sixteenth century monument, suffering from structural cracks that had occurred in recent years. Its aim was to discover the thermal behaviour and ultrasonic characteristics of cracks in relation to depth and moisture content. The superficial and deep cracks were found to have different thermal responses to exposed conditions which made them easily distinguishable by QIRT analyses. The results of thermal monitoring during the exposure of heating conditions were promising in giving hints of methods for the depth assessment of deep cracks in masonry. The in situ ultrasonic data taken in indirect transmission mode provided knowledge on the depth of cracks that enhanced the accuracy of the non-destructive in situ survey.
