Corrosion of Reinforcing Steel Bars in Concrete

Abstract

THE USE OF DEICING SALTS TO REMOVE ICE AND SNOW FROM HIGHWAYS, STREETS AND BRIDGE DECKS HAS CAUSED SERIOUS CORROSION OF REINFORCING STEEL IN CONCRETE. THE STRUCTURE OF REINFORCED CONCRETE IS SIMULATED IN CELL DESIGNS AND THE EFFECT OF CORROSION IS SHOWN. THE AUTHORS DISCUSS THE EFFECTS OF MILL SCALE AND DIFFERENTIAL AERATION, SEVERAL INHIBITORS TESTED, AND VARIOUS POSSIBLE METALLIC AND NONMETALLIC COATINGS FOR STEEL. /AUTHOR/
