Segmentation of X-ray tomographic images : contribution to weathering analysis of building limestones originating from historical buildinds.
Abstract : Historical monuments contributing to our cultural heritage undergo their environment that alters them and can results in their destruction. The observed macro-scale effects result from physico-chemical mechanisms (dissolution, transport, precipitation) occurring in the complex porous structure of the building stones at the pore scale. Understanding of weathering processes and more generally of water transfer properties of building stone requires a detailed knowledge of the pore and different solid phases distribution. Indeed, quantitative physical models (permeability, compressive strength...) rely on a precise and relevant description of the microstructure. The method presented here is a required step toward the understanding of the mechanisms of limestones weathering based on realistic geometrical information of the geomaterial, i.e. not based on a more or less complex mathematical model representing an ideal material.
