Low Permeability of Concrete for Bridge Deck Overlay

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 ...
