Title: Improvement of Concrete Durability Against Intrusion of Chloride-Laden Ws Admixtures
Author(s): Stella L. Marusin
Publication: Special Publication
Appears on pages(s): 599-620
Keywords: admixtures; chlorides; coatings; concrete durability; plasticizers; sealers; silica; tests; Materials Research
Abstract:Research since 1979 on sealers, coatings, and concrete containing admixtures is summarized. A test procedure developed during a National Cooperative Highway Research Program project, "Concrete Sealers for Protection of Bridge Structures," was used. This test method uses 10 cm cube specimens, and water absorption and chloride ion penetration is determined after 21 days of exposure to 15 percent NaCl solution. The study focuses on the minimization of the ingress of chloride-laden water into concrete, the influence of water-cement ratio, the relationship between water absorption and chloride ion content in concrete, and the comparison of the chloride distribution profiles through the conventional portland cement concrete and concrete containing various admixtures (superplasticizers, polymer emulsions, condensed silica fume).
