Reasons and prevention of corrosion-induced failures of prestressing steel in concrete
by U. Nuernberger
International Journal of Structural Engineering (IJSTRUCTE), Vol. 1, No. 1, 2009

Abstract: Serious damages in post- and pretensioned prestressed components have occurred due to hydrogen-induced stress corrosion cracking of prestressing steel. The failures happened due 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 of prestressing steel and gives an overview about the knowledge concerning prevention methods for application in contact with mortar and concrete.
