AN INTERDISCIPLINARY APPROACH FOR THE HISTORICAL AND TECHNICAL CHARACTERIZATION OF MEDIEVAL AND MODERN MORTARS

The study concerns Italian masonries and focuses on historical, medieval and modern mortars. Within the context of the different regions under examination (Piedmont, the Po Valley area, Latium, the Umbria-Marche region, and Apulia and Sardinia) a wide variety of materials with different chemical-physical characteristics were used in masonry work, determining different structural behaviors. The project aims at improving our knowledge about historical mortars in order to further the conservation of Italian built heritage, especially in zones with seismic risk. To achieve these results, we took samples and carried out analyses to investigate the different mechanical and cohesion properties that influence the vulnerability of ruined or collapsed structures.
