Conservation Techniques and Studies

In this paper, we investigate a conservation treatment on different kinds of Agrigento's biocalcarenites, introducing a new non-commercial aqueous nanolime suspension for compatible and eco-friendly extensive applications. This nanolime, here tested for the first time, can be considered a green treatment for both the environment and the health of the conservator. Petrographic, chemico-physical and mechanical investigations of the different biocalcarenites were carried out before and after treatment application. This new nanolime yielded a very promising consolidation effectiveness for all the biocalcarenites, increasing the superficial cohesion and the drilling resistance without significantly altering the stone porosity or the aesthetical features.
