Once the current state of decay was diagnosed and the processes of alteration (enhanced by certain intrinsic factors and their particular exposure to the environmental conditions) were detected, a pre-restoration experimental assay was conducted. On the one hand, to propose the best stone replacement, this study evaluates the compatibility of the available sandstones in the local market based on their intrinsic features, especially those related to hydric behaviour. Once the most suitable sandstone was selected, pore size distributions were determined along with accelerated ageing cycles to show the importance of selecting properly the potential replacement sandstone. In a second step, to determine the effectiveness and long-term efficacy of four water-repellent products, several on-site and laboratory tests were performed. From the experimental results obtained, remedial works have been proposed which will be useful not only for the restoration programme of this monument, but also for other emblematic architectural Heritage in the Ebro Valley. info:eu-repo/grantAgreement/ES/DGA/E20-17R info:eu-repo/grantAgreement/ES/DGA-FEDER/Construyendo Europa desde Aragón info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 1.9 2024 0.449 2024 Archeology (arts and humanities) 2024 Q1 Conservation 2024 Q1 Materials Science (miscellaneous) 2024 Q2 3.7 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Cuchí Oterino, José Antonio Universidad de Zaragoza (orcid)0000-0001-9067-2940 Auqué Sanz, Luis Francisco Universidad de Zaragoza (orcid)0000-0003-1463-1682 2000 685 Universidad de Zaragoza Dpto.
