Korrosionsinhibitoren für die Instandsetzung chloridverseuchter Stahlbetonbauten

Corrosion Inhibitors for the Rehabilitation of Chloride Contaminated Reinforced Concrete Structures

The use of inhibitors is considered worldwide as a technically and economically interesting alternative to the conventional repair of reinforced concrete structures since the removal of concrete can be considerably reduced or completely omitted. In this contribution the results of practical laboratory investigations are presented (active, e.g. ongoing corrosion, different concrete cover depths and chloride contents of the substrate or "old concrete", macroelement effect). None of the three tested systems was able to reduce the corrosion rate or to stop the corrosion.
