Korrosionsprodukte und deren Volumenfaktor bei der Korrosion von Stahl in Beton

Corrosion Products and their Volume Factor Created by Corrosion of Steel in Concrete

Steel corrosion is one of the main reasons of degradation and damage of concrete structures. The volume of rust, resulting from steel corrosion, can be several times greater than the original steel volume which leads to cracking and spalling of the concrete and may finally end in the loss of structural functionality. Based on corrosion experiments on black steel, this article presents the major components of typical oxide layers and their volume expansion and thus forms a basis for further studies on corrosion of steel in concrete.
