Title: Study of the Penetrating Process of Chloride Ions into Concrete
Author(s): Y . Yamada, T. Oshiro and Y. Masuda
Publication: Special Publication
Appears on pages(s): 331-346
Keywords: Carbonation, chlorides; diffusion
Abstract:This paper presents an empirical equation representing the relation between the amount of air laden chlorides reaching a concrete surface and the rate of chloride ions penetrating into concrete. By using this proposed equation as a boundary condition, an analytical diffusion model is presented, where various factors such as water-cement ratio (w/c), carbonation depth, and lapse of time after construction are considered. Comparing the analytical results obtained from the proposed model with the experimental results, the effectiveness of this proposed model is confirmed.
