Abstract

Travertine pillars in the court of the colegiata del Salvador (s. XVI) bear damaged surfaces that were recovered with concrete mortars. This material induced further mechanical and chemical damage in the travertine due to the enhanced capillarity rise resulting from the contrasting thermal behaviour and porosity. Sinthetic mortars (epoxi and PMMA) yielded very low total porosity (2-5%). Thus, in addition to removing the concrete mortars and salts, cleaning, and consolidation (acrylic resins and alchil-aril-polisiloxanes), we propose recovering the eroded surfaces with mixed mortars with the appropiate porosity.
