CASE STUDIES

摘要

The reinforced concrete piers of this motorway viaduct had deteriorated due to carbonation and erosion by chlorides found in de-icing salts. Concrete cracking led to the reinforcement debonding, requiring up to 120 mm of the surface to be removed.rnSteel mesh and self-compacting concrete were placed to repair the piers, which are up to 140 m tall - some of the tallest in Europe. After sandblasting, Mapelastic was applied to create the final protective layer.
