Resumen de Microestructura de la arenisca de las Catedrales de Salamanca: alteración diferenciada

María Teresa Martín Patino, Fernando Madruga Real, Julio Saavedra Alonso

• The Villamayor sandstone, used as a building material for the cathedrals of Salamanca, presents different degrees of deterioration in areas where the conditions of location and environment are identical. There are no appreciable differences respect to mineral, chemical and physical-mechanical characteristics which justify this fact. The textural anisotropy and the internal microstructure of these stones give the answer to this question.
