Nanosilica-based consolidants are promising nanostructured strengthening agents mainly used for consolidation of mortar and cements. Their use shows some positive aspects that encourage their application in stone consolidation field. Several preliminary studies underline that the nanosilica particles increase the reactivity and the penetration depth than other products having a great effect on silicate stone [1]. In this context, the aim of the present work is to formulate a specific nanosilica product suitable for the consolidation of Bianco Sardo, Pietra di Firenzuola and Pietra di Muggia. In this study, two phases have been underlined: (i) the synthesis of the nano-compound, (ii) the application of the product synthetized for the consolidation purpose.

Abstract
Nanosilica-based consolidants are promising nanostructured strengthening agents mainly used for consolidation of mortar and cements. Their use shows some positive aspects that encourage their application in stone consolidation field. Several preliminary studies underline that the nanosilica particles increase the reactivity and the penetration depth than other products having a great effect on silicate stone [1]. In this context, the aim of the present work is to formulate a specific nanosilica product suitable for the consolidation of Bianco Sardo, Pietra di Firenzuola and Pietra di Muggia. In this study, two phases have been underlined: (i) the synthesis of the nano-compound, (ii) the application of the product synthetized for the consolidation purpose.
