PENETRATION OF CHLORIDE FROM DE-ICING SALT INTO CONCRETE FROM A 30 YEAR OLD BRIDGE
2000
This paper presents the analysis of chloride profiles obtained from a reinforced concrete bridge. For an extended period, this bridge was exposed to de-icing salts. The bicycle lane was coated with an epoxy coating and the side walks were left uncoated. A total of 36 chloride profiles were analyzed using a diffusion model. Chloride diffusion coefficients describing the penetration of chloride were derived for both the coated and uncoated portions of the bridge. Results are provided and discussed.
