In the present work a nanolime, to be used in Cultural Heritage Conservation, is produced in order to evaluate its effectiveness on the conservation of some Italian sandstones. Lime nanoparticles are produced by a chemical precipitation process in supersaturated aqueous or alcoholic solutions of reactants. Then, they are characterised by transmission electron microscopy; hexagonal particles of dimension ranging from 50 to 600 nm are obtained. After that, the lime nanoparticles are applied on natural sandstones (Campolo and Grelio sandstones) and some tests are performed in order to estimate the consolidating effect of the treatment: “Scotch Tape Test”, “Surface abrasion test”, capillarity and imbibition tests, compressive strength and mercury intruded porosimetry.

Abstract

In the present work a nanolime, to be used in Cultural Heritage Conservation, is produced in order to evaluate its effectiveness on the conservation of some Italian sandstones. Lime nanoparticles are produced by a chemical precipitation process in supersaturated aqueous or alcoholic solutions of reactants. Then, they are characterised by transmission electron microscopy; hexagonal particles of dimension ranging from 50 to 600 nm are obtained. After that, the lime nanoparticles are applied on natural sandstones (Campolo and Grelio sandstones) and some tests are performed in order to estimate the consolidating effect of the treatment: “Scotch Tape Test”, “Surface abrasion test”, capillarity and imbibition tests, compressive strength and mercury intruded porosimetry.
