New nanomaterials for protecting and consolidating stone elena models dating agency
Recently the employment of nanolime in the consolidation treatments of decorative carbonate matrix surfaces had a great development, thanks to multifunctional use in calcium standard-sized particles treatments.
However, while the use of the nanostructured materials is described in several specialized papers, the information about the best conditions of applicability of the nanolime and its related potentiality for the consolidation in hypogeum environment is rarely considered.
The team also invented new ways to assess damage to stone and refined a number of existing techniques.
Enhanced salt weathering resulting from global warming and increasing environmental pollution is endangering the survival of stone monuments and artworks.
To mitigate the effects of these deleterious processes, numerous conservation treatments have been applied that, however, show limited efficacy.
This involves a series of partially unsolved problems, concerning the products used for deteriorated structures consolidation.
The choice of materials depends on several factors such as: microclimatic conditions, application methods, and reaction time of products.
Moreover, some of these conventional treatments are not environmentally friendly because they release toxic chemicals, and the treatments themselves can undergo degradation (e.g., biodeterioration of organic polymers).
