TNO Bouw Contributor Wittmann, F.H. (editor) Publication year 1998 Abstract The subject of this study was the performance of hydrophobic treatment to protect concrete against chloride penetration from de-icing salts. Hydrophobic treatment makes a concrete surface absorb less water and less chloride. Several types of tests were carried out to study the performance of hydrophobised concrete. Salt ponding/drying tests showed that the penetration of chloride can be reduced by about 80% due to hydrophobic treatment. The water repellent effect remained constant over three years outdoor exposure. Corrosion which had already started before application of the hydrophobic agent was not influenced by hydrophobic treatment. No effect of hydrophobic treatment was measured on carbonation. Long term absorption tests with drinking and salt water showed significant less absorption by hydrophobic concrete.
