摘要: A novel alkoxysilane-based product was applied on limestone samples from a Roman archaeological site. The study consisted of an initial phase to evaluate site environmental conditions in order choose the most suitable type be applied. decay that produced is mainly caused by natural action, with water being main vehicle for agents. Thus, effectiveness innovative hydrophobic/consolidant properties and two commercial products (consolidant hydrophobic agent) were evaluated Acinipo site, under laboratory conditions. Next, long-term three exposure period years. Since recognized incompatibility between alkoxysilanes pure carbonate stones, interaction limestones widely investigated. results obtained allow it concluded presents adequate compatibility adherence study, producing effective, homogeneous, continuous coating depth penetration up 10 mm. However, discontinuous aggregates surface, did not penetrate into its porous structure produce long-lasting effects.
