REASONS AND PREVENTION OF CORROSION INDUCED FAILURES OF PRESTRESSING STEEL IN CONCRETE
Serious damages in post-and pretensioned prestressed components have occurreddue to hydrogen induced stress corrosion cracking of prestressing steel. The failures happeneddue to onsite conditions and were favoured by the sensitivity of the steels towards hydrogen.The contribution describes the mechanism of the fracturing process,the corrosion testing ofprestressing steel and gives an overview about the knowledge concerning prevention methodsfor application in contact with mortar and concrete.
