TNO Bouw Publication year 1999 Abstract Penetration of de-icing salts into concrete bridge decks may cause corrosion of reinforcement. Hydrophobic treatment of concrete was studied as additional protection. It was shown that hydrophobic treatment strongly reduces chloride ingress, during semi-permanent contact and in wetting/drying situations. The protection remains effective for at least five years. Carbonation of concrete is not significantly accelerated. Hydrophobic treatment does not stop corrosion if initiation by chlorides has already taken place before the treatment. Criteria for testing hydrophobic agents are available. Hydrophobic treatment is an effective, low cost preventative measure against corrosion of reinforcement. It has become standard for all new concrete bridge decks in The Netherlands.
