Title: Proformance of Galvanized Reinforcement in Calcium Hydroxide Solution
Author(s): M. Unz
Publication: Journal Proceedings
Appears on pages(s): 91-99
Keywords: calcium hydroxides; cholorides; corrosion; corrosion resistance; corrosion tests; galvanic corrsion; immersion tests (corrosion); reinforced concrete; reinforcing steels; zinc coatings.
Abstract:Galvanized steel is passivated by the saturated calcium hydroxide solution contained in moist concrete. Inherrent corrsion currents develop, however, at excessive cholride contents and under conditions of nonuniform exposure. These currents lead to local chloride accumlation with intensive pitting, regardless of exisisting passivation films. The corrsion resistance of galvanized steel reinforcement has been compared with that of bare steel.
