Possibilities of Using Calcium Hydroxide-based Nanomaterials in the Care of Historical Surfaces

Original language description

Consolidation of historic lime plasteres which have degraded binder component, disturbed structure, insufficient adhesion of individual layers to the masonry surface, with increased salt content in the pore system and surface crusts is a challenging task. At present, the consolidation of degraded lime plasters is carried out with consolidants which are applied in the form of solutions, in particular lime water, organosilicates or lime nanosuspensions, etc. The use of nanosuspensions (based primarily on calcium hydroxide), which today is one of the proven technologies used to strengthen degraded plasters, occurs, as with fresh lime plaster, carbonation, where calcium hydroxide reacts with atmospheric carbon dioxide to form calcium carbonate. Due to the deposition of calcium carbonate in the incoherent material, the bonds are reinforced and strengthened. Compared to lime water, the low number of impregnation cycles represents an indisputable advantage of consolidating plasters by lime nanosuspensions, where after several applications of the nanosuspension the disrupted material is strengthened. The paper presents partial results of theoretical and experimental research focused on the possibilities of consolidation of historical surface layers (plasters) using lime water and newly developed lime nanosuspensions prepared by synthesis of Ca(OH)2, which were subsequently modified and enriched with other components.
