Characterization of repair mortars for the assessment of their compatibility

Abstract eng:
Compatibility requirements for repair mortars used in restoration works are defined based on the original mortar characteristics, but the quality and the performance of the repair mortars after application on masonry are generally not assessed. From this perspective, original mortars and their repair mortars from three historic masonry structures were characterized to assess their compatibility in terms of chemical, mineralogical, physical and mechanical point of view. A methodology relying on a fundamental approach for a mortar analysis is adopted taking into account the added values and the basic requirements from both practical and scientific point of view. This study is aiming to contribute to the existing knowledge on mortar characterization and to provide new insights on the assessment of the compatibility of the repair mortars.
