Weathering of limestone after several decades in an urban environment
Corrosion Science(2016)
摘要
•The chemical and physical parameters of limestone exposed during more than 60 years in an urban environment are characterized at different scales.•From a chemical point of view, the alteration leads to an in-depth sulfur enrichment neoformation of gypsum and to a surface carbon deposit.•The weathering rate is highly dependent on the position of the block on the monument.
