Resumo
Maintenance and rehabilitation are important measures to preserve the historical tiles of facade.
In the materials rehabilitation context, is fundamental the knowledge of the original materials
characteristics. Facing that, this research aimed to characterize the tile/mortar interface in
samples of facades from Ovar – Portugal, in the period between the nineteenth and twentieth
centuries. For this purpose, initially were realized several tests and evaluations to characterize
samples of mortars (XRD, petrographic and chemical analysis, TGA, SEM and carbonation
depth) and glazed tiles (XRD, MIP and water absorption). Posteriorly, the tile/mortar interface
was analyzed in mesostructural level (stereo microscope) quantifying the mortar’s extension
adhered to the underside of the tile. As result of these analyses, was observed that the extension
of adherence is related to the characteristics of the aggregates of the mortars and to the
configuration of the underside of the tile and not to the binder/aggregate ratio of the mortars.
