Silica‐Functionalized Nanolimes for the Conservation of Stone Heritage

Small, 2023
AbstractThe relatively recent development of nanolimes (i.e., alcoholic dispersions of Ca(OH)2 nanoparticles) has paved the way for new approaches to the conservation of important art works. Despite their many benefits, nanolimes have shown limited reactivity, back‐migration, poor penetration, and lack of proper bonding to silicate substrates.

Effectiveness of Nanolime as a Stone Consolidant: A 4-Year Study of Six Common UK Limestones [PDF]

, 2019
Protecting stone buildings from weathering and decay is a major challenge in the conservation of built heritage. Most of the stone consolidants currently available are well suited to silicate stones, but are less compatible with limestone.
