Title: Effect of Surface Coatings on the Durability of Concrete Exposed to Marine Environment
Author(s): T. Oshiro and S. Tanigawa
Publication: Special Publication
Appears on pages(s): 179-198
Keywords: accelerated tests; buildings; chlorides; coatings; exposure; concrete durability; diffusion; field tests; marine atmospheres; weathering; Materials Research
Abstract:A test building constructed in 1984 was exposed to marine environment under sub-tropical weather of Okinawa, Japan. Concentration of chloride ions in concrete, changes in the half cell potentials with time, and protective effects of surface coatings were investigated. Diffusion of chloride ions was monitored using Fick's law. The diffusion equation was converted to difference equation and solved under the initial condition in terms of time. These results were compared with those of the field, and the relationships were obtained.
