Micromechanical and microstructural properties of natural stones used in historical buildings

Popis výsledku v původním jazyce

In this paper combination of advanced experimental and numerical methods for micromechanicalnand microstructural characterization of natural stones used in historical buildings isnpresented. Several different types of porous stones commonly used for construction of builtnheritage as well as for restoration purposes were subjected to complex experimental investigationninvolving SEM imaging, EDS based identification of chemical composition, nanomechanicalnmeasurement of properties of constituent phase and experimental measurementsnof fluid uptake characteristics. Using a combination of image and signal processing techniquesnapplied on SEM micrographs dimensions of representative volume element of investigatednmaterials were determined. Real-time X-ray radiography utilizing state-of-the-artndual source/dual energy setup was used for observation of fluid penetration process in Maastrichtnlimestone and to develop a detailed voxel model for numerical simulations of investigatednphenomena. Using such methods methodology for description of important factors influencingnsustainability of historical buildings was established.
