CORROSION OF GALVANIZED STEEL IN CONTACT WITH CONCRETE CONTAINING CALCIUM CHLORIDE

Rapid corrosion of galvanized steel sheets used as permanent forms for concrete containing calcium chloride is described. While most applications of galvanized steel for this purpose experience little or no difficulty, when excess water is present in the mix and surfaces are sealed or occluded to prevent evaporation, rapid attack on the galvanized metal occurs. Case histories are related of damage resulting from excess moisture, and application of heat to the slab which accelerates the attack. /Author/
