Estudio de indicadores y mecanismos de alteración de los atauriques del muro de fondo del Salón Rico de Madinat Alzahra : Córdoba

Abstract

The characterization of the materials both original and those used to reconstruct the building and the alteration products has been carried out by means of chemical analysis of major components, X Ray diffraction and optical microscopy of cross section. Most important weathering indicators that appear on the Wall are: disagregation, crusts, efflorescences. The weathering mechanisms that act over the Wall are mainly salt crystallization and termohygrometric cycles, and in a little extend, chemical reaction between the components of the stone and the soluble salts.
