Résumé : |
Steel reinforced concrete bridge components are deteriorating prematurely, especially in marine and snow/ice zones of the U.S. The primary cause of this deterioration is chloride intrusion into the concrete. The authors discuss research that has shown that penetrating sealers can provide some protection to the concrete but are not as effective as thin-film coatings in retarding chloride intrusion. |
