Low carbonation of concrete found on 100-year-old bridges
This work investigates an unexpectedly low carbonation depth found in two bridges. A protection against carbonation is ensured by approximately 2–3 mm thick dense plaster coat covering the outer surface of concrete.

| Summary: | This work investigates an unexpectedly low carbonation depth found in two bridges. A protection against carbonation is ensured by approximately 2–3 mm thick dense plaster coat covering the outer surface of concrete. The plaster coat consists prevailingly of compact carbonate micro particles, showing no open pores and such a density, which gives this extremely thin layer non-permeability property for carbon oxide penetration over time.
