Mortar Characterization of Historical Masonry Damaged by Riverbank Failure: The Case of Lungarno Torrigiani (Florence)

The research of structural masonry associated with geo-hydrological hazards in Cultural Heritage is a multidisciplinary issue, requiring consideration several aspects including the characterization used materials. On 25 May 2016, loss water from subterranean pipes and aqueduct caused an Arno riverbank failure damaging 100 m long portion historical embankment wall Lungarno Torrigiani Florence. was built 1854–1855 by Giuseppe Poggi represents example engineering approach to construction, composed scarp massive on foundation piles, rubble internal core. event only cusp-shaped deformation without any shattering or toppling. A complete mortars performed identify technologies, raw materials state conservation order understand why has not collapsed. Indeed, utilized influenced behavior masonry, their fundamental improve knowledge mechanical properties civil architectural heritage walls. Therefore, aim this analyze mineralogical–petrographic, physical points view, evaluate contribution damage events. Moreover, results study helped compatible project solutions for installation hydraulically statically functional structures contain riverbank.
