Trattamenti consolidanti di mattoni in ambiente marino.

The study starts from a wider experimentation project about binding and protective products, applied to different materials, in a marine environment. The project has been realized during the San Fruttuoso Abbey restoration work in Camogli (Genoa). The present paper aims to propose the part of the experiment concerning the use of binding products on the sea front clay brick arch of the Abbey. The project was divided into two different phases. The first one was focused on two main purposes: the bibliographic recognition about the material concerning cases similar to the one object of the consultancy, and the market research about binding products currently available on the Italian market. The second one was focused on acquiring technical data on binders products, selecting the most suitable ones, and their direct experimentation. The experimentation was carried out on a clay brick surface portion of an outer arcade, selected due to the presence of different types of bricks and because of its interesting and complex masonry stratigraphy. The over time efficacy of the products was evaluated through a series of tests carried out in two different monitorings. Comparing the different data emerged from the bibliographic research, the experimentation and the macroscopic evaluations, carried out some interesting considerations about potentialities and methods of intervention on clay brick masonry in the marine environment.
