Many investigations have been conducted to study the mechanism(s) of corrosion of steel in concrete and the effects and influence of pH, chloride ion concentration, and oxygen availability. Roberts1  studied the effects of CaCl2 additions on the corrosion of steel wires embedded in concrete made from Portland and Portland, sulfate-resisting cement. He concluded that the amount of CaCl2 which could safely be added to the concretes was dependent upon the curing and exposure conditions. In additional studies Roberts attempted to find a threshold concentration of CaCl2 below which the corrosion of steel in concrete would not be significant. No positive evidence for a threshold concentration was found.
