Title: Influence of Superplasticizers, Polymer Admixtures, and SilicaFume in Concrete on Chloride Ion Permeability
Author(s): S. L. Marusin
Publication: Special Publication
Appears on pages(s): 19-34
Keywords: admixtures; chlorides; concretes; epoxy resins; latex; permeability; plasticizers; plastics, polymers, and resins; silica fume; Materials Research
Abstract:This paper summarizes the results of permeability studies that have been undertaken since 1979. The research used a test procedure developed during the NCHRP Project 12-19A, "Concrete Sealers for Protection of Bridge Structures", which was reprinted in 1981 as NCHRP Report No. 244. This test method utilizes 10 cm concrete cubes, and chloride ion penetration is determined at 4 depths after 21 days exposure to 15 percent NaCl solution. The test results show that lowering of water-cement ratio in portland cement concrete or presence of superplasticizers, polymer admixtures, and silica fumes are able to significantly reduce concrete permeability.
