Abstract

Mortars for intervention in monuments and historical buildings I. Papayianni & M. Stefanidou Department of Civil Engineering, Laboratory of Building Materials, Aristotle University of Thessaloniki, Greece Abstract The main problem in designing repair mortars for monuments and historical buildings is their compatibility with the old ones. Many parameters such as colour, texture, porosity, composition, size and type of aggregates as well as mechanical characteristics influence this compatibility. In the framework of many research projects sponsored by the Greek Ministry of Culture and European Committee, a great number of ancient mortars (from monuments of different historical periods) have been analyzed at the Laboratory of Building Materials of Aristotle University of Thessaloniki. Their composition, the physicochemical properties as well as their behaviour were found and studied systematically. Therefore, much experience has been accumulated. Based on this experience a long-term experimental
