Durability of repair mortars used in restoration of a Sardinian coastal tower: assessment after ten years
[EN] This study reports the results of investigations on conservation conditions of an ancient tower, called
Torre del Pozzo, located in the S-W coast of Sardinia, restored about ten years ago. The tower suffers
from serious problems related to vulnerability of building materials, particularly limestone and
sandstones and aerial lime mortar with poor physical-mechanical properties. Over the centuries the
materials were subjected to aggressive actions (wind corrasion and salt crystallization) causing an
intense erosion of the walls with consequent partial collapse of the structure. About ten years ago a
restoration involved the mortars and only the replacement and integration of ashlars deteriorated. After
about 10 years from this intervention, some inspections have been carried out in order to assess the
effectiveness of the intervention and the state of preservation of the tower. This paper focuses on
analyses and tests carried out to assess condition and durability of the repair mortars.Meloni, P.; Carcangiu, G.; Palomba, M.; Enzo, S.; Carboni, M.; Cocco, O.; Casti, M.... (2015).
