Research Abstract	Research has been focussed to the synthesis of calcium hydroxide nano-particles. Deacidification of kozo and gampi Japanese papers and western type acidic wood pulp paper with non-aqueous nano-lime is effective. Effectivity is about the same then that of common(normal) lime. The consolidation of mortar, brick and" artificial" stones(sandstone, granite and tuff), and comparison with traditional consolidants : Final evaluation can' t be given because carbonatation of nanolime was completed only in a 2-3mm thick surface layer in three month. As temporary result nano-lime is especially promisable for the consolidation of sandstone and tuff" artificial stones" used in the study. Consolidation(splitting tensile strength) is about the same than that of Paraloid and higher than that of Wacker and Araldite treated. After full carbonatation results will be re-evaluated.
