| 摘要： | The Minnesota Department of Transportation (Mn/DOT) occasionally uses concrete sealers to improve the surface characteristics of bridge decks or other concrete exposed to the environment. The application of sealers may become more common in the future as a preventative maintenance tool. Laboratory screening tests have identified a number of sealers, both penetrating and surface film-forming, that showed promise at reducing moisture and chloride ion penetration. Performance data from the field are lacking. The goal of this study was to evaluate the effectiveness of concrete sealers applied to a bridge deck. Sixteen different concrete sealers, plus an untreated control section, were tested for a period of three years. The test site was a new bridge deck with a low slump dense concrete overlay. Concrete drill dust samples were collected annually from each test section to determine chloride penetration into the deck. The data collected determined the relative effectiveness and service life of the various sealers. |
