Low Permeability of Concrete for Bridge Deck Overlay,

The penetration of chloride ions from deicing salts into the portland cement concrete of bridge decks can cause corrosion and serious damage to the reinforcing steel. Concrete properties which prevent chloride penetration into the bridge deck and provide a good structural and economic wearing surface are desirable. A variety of mix designs have been tried in the past in search of improved ...

Chloride Permeabilities of Rigid Concrete Bridge Deck

study of the chloride permeability of rigid concrete bridge deck overlays was conducted during the 1987 construction season. A total of thirteen latex-modified concrete (LMC) overlays, ten superplasticized dense concrete (SDC) overlays, and two condensed silica fume concrete (CSFC) overlays, were investigated. Concretes were tested both by the rapid chloride permeability test and by 90-day
