Résumé
We report the results of analyses of a granite ashlar extracted during a restoration work from the cloister of the Monatery of San Martín Pinario (Santiago de Compostela, Spain). Petrographic, mineralogical and geochemical analyses were supplemented by determination of physical properties governing water transport in the stone (open porosity, degree of absortion and saturation, and capillary coefficient), compressive and bending strength and termal dilation coefficient and swelling coefficient. These fundamental characteristics of building stone may throw light on its response to diverse weathering mecanisms.
