Corrosion protection for reinforcing steels in prefabricated concrete elements

Objective of this cooperative research project was the development of organic covers as corrosion protection for reinforcing steels capable to withstand chloride solutions as well as aquaous solutions with pH values between 7 and 14. In addition a deposition technology should be devised to apply the protective layers after welding operations in the course of the production process of prefabricated reinforced concrete elements. A total of 35 different protective layers were tested with regard to corrosion resistance in a salt spray test arrangement similar to DIN 50021. Since the results were disappointing, as well with respect to the application techniques as with respect to corrosion resistance, the project was discontinued. not assigned KP: HR Dipl.-Ing.
