Title:
Abstract:	In dem hier vorgestellten Forschungsprojekt wurden durch die TU Dortmund, die MPA Darmstadt und das Institut für Korrosionsschutz Dresden GmbH der wissenschaftliche und technische Nachweis eines sicheren Einsatzes der Feuerverzinkung im Stahl- und Verbundbrückenbau erbracht (Teil 1 s. Stahlbau, H. 1/2015). Durch Laborbelastungen und Freibewitterung konnte die Korrosionsschutzwirkung der Feuerverzinkung für bis zu 100 Jahre, d. h. über die gesamte rechnerische Lebensdauer einer Brücke hinweg, nachgewiesen werden. Durch zusätzliche Entwicklung einer Ausführungsanweisung für Montagestöße können damit die ökologischen und ökonomischen Vorteile gegenüber den aktuell eingesetzten Korrosionsschutzsystemen genutzt werden. Hot-dip galvanizing in bridge construction - Part 2: Using hot-dip galvanizing as a lifetime corrosion protection for bridge constructions. In the here presented research project the scientific and technical evidence for the safe use of hot-dip galvanizing for steel and composite bridges were provided by TU Dortmund, MPA Darmstadt and Institut für Korrosionsschutz Dresden GmbH. By laboratory tests and natural weathering the evidence of the corrosion protection of hot dip galvanizing for up to 100 years, i. e. over the entire calculated life of a bridge, could be provided. With the additional developed design guide for mounting joints the environmental and economic advantages over the currently applied corrosion protection systems can be used.
