Assessing the self-healings properties of nano -Ca(OH)₂ – TiO₂ – ZnO materials used in monuments conservation works

Abstract Consolidates based on Ca(OH) 2 have been prepared as macro- and/or nanoparticles dispersed in different alcohols, regardless of the precursor nature. Their efficiency is related to small dimensions particles and dispersion media, which allows their penetration into deteriorated material substrates, well an increased reactivity towards CO . Besides consolidating effect there a strong need for newly developed materials also tackle other properties like self cleaning antimicrobial activity, especially with regards white monuments. In this context present work highlights treating stable alcoholic suspension containing nano - – TiO ZnO physical support models consisting mortar cubic samples from hydraulic / aerial lime, commonly used consolidation works.
