Preserving the Great Mosque of Cordoba (Spain): A Preliminary Mechanical Characterization of Its Original Natural Stone

Abstract

The Mosque of Cordoba (Spain) is an emblem of the rich cultural heritage of Western Andalusia. This research focuses on the mechanical characterization of the natural stone used in the building. Determining its properties is crucial to understanding the structural behaviour of the entire building. An experimental campaign with various mechanical tests, such as density, compression, indirect tensile, and bending tests, was conducted on more than 100 cubic and prismatic specimens obtained from the main quarry that supplies material for the mosque’s restoration. The results indicated the stone’s isotropic behaviour for the studied properties. Further analysis established correlations between compressive strength (averaging 6 MPa) and other mechanical properties. This preliminary characterization provides valuable information for future in situ testing and more sophisticated lab techniques.
