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. Test methods and requirements for commercial products were established. In most cases, the water absorption was strongly reduced and the penetration depth could be well over 2 mm. Several types of tests were carried out to study the perforrnrice of hydrophobised concrete. After 52 weekly salt ponding/drying cycles the penetration of chloride was 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
