Abstract

In this work, infrared thermography is employed with the intention of evaluating the moisture distribution by capillary rise in reference porous material specimens in the laboratory, in an attempt to substantiate the investigation of real scale material systems in situ. The assessment of repair mortars, in lab and in situ on historic monuments in Greece, permits to evaluate the performance of conservation materials, regarding their compatibility to the porous building stones on historic masonries. Furthermore, the study of water evaporation transport phenomena in prototype simulating porous materials under stable environmental conditions (Relative Humidity & Temperature) by the use of infrared thermography provides essential information by becoming the key element in order to interpret the transport phenomena occurring at the masonry. It is assumed that infrared thermography by recording thermal images of the genuine surfaces under survey provides valuable information on the differential behaviour of the different materials on the masonry scale concerning the water saturation and evaporation phenomena, which trigger the weathering effects in porous materials. Consequently, infrared thermography can be exploited as a non-destructive technique, with the intention of assessing the performance of conservation interventions and materials, in compatibility to the authentic building materials on the level of the structures.
