Abstract: The paper discusses the mechanisms of zinc corrosion in contact with concrete with special emphasis on post-installed fasteners. Experimental results on the influence of cement type,carbonation, galvanic effects and results of exposure tests up to ten years are presented. Compared to corrosion of galvanized reinforcement embedded in concrete and galvanized metalwork exposed to the atmospere, differences in mechanism and type of corrosive attack are found. In case of weathered concrete, even hot dip galvanizing does not assure corrosion protection for more than ten years because of localized attack due to galvanic effects at the interface concrete/atmosphere.
