Convection and diffusion zones in chloride penetrations profiles in reinforced concrete structures
Zones of convection and diffusion of chlorides at penetration of chlorides into a reinforced concrete structures are considered. Many experimental chloride penetrations profiles have a convection zone in external layer of concrete where the fit between the profile and error-function is bad Is shown that the size of a convection zone is 5-18 mm and lager for flying structures in comparison with columns.
