Corrosion of High-Chromium and Conventional Steels in Concrete

Corrosion of steel in concrete structures sometimes led to the unexpected failure of the concrete bridges in United States before their intended service life. High-chromium steel has been developed as a replacement for conventional steel in concrete because it may have a capability to retard the corrosion rate. In the present study, high- chromium and conventional steels were subjected to accelerated corrosion, and compared for their corrosion performance under chloride environment. The study provides information on the sensitivities of these steels with respect to different chloride concentrations and the presence of various minerals associated with the corrosion products which should explain the distinct corrosion rates between the two steel rebars. This study should be especially useful to Professionals in Structural and Bridge Engineering
