Constructions made of porous rock may weather over time. TU Wien (Vienna) researchers have now thoroughly examined how silicate nanoparticles can help save them for the first time.
Several historical buildings were made of limestone, such as Vienna’s St. Stephen’s Cathedral. Limestone is simple to work with but does not resist weathering well. It comprises primarily of calcite minerals that are comparatively bound weakly to each other. This is why parts of the stone tend to keep disintegrating over the years. This often needs expensive conservation and restoration treatments.
