Polymeric and cementitious mortars for the reconstruction of natural stone structures exposed to marine environments

This study outlines the advantages and disadvantages of the use of composites in reconstruction activities. The aim of the study is the reconstruction of a natural rocky arc exposed to a marine environment. Anchoring reinforcements of two types of stainless steel were analyzed. Also epoxy resins, polymeric, cement based mortars and cement based concrete, separately and in combination, have been studied. Durability, mechanical behaviour, protective effect of mortars and thermal compatibility were studied. The overall conclusion of the research is that polymeric mortars are the most appropriate for the reconstruction and/or rehabilitation of stone structures exposed to highly corrosive environments.
