DETERMINATION OF CHLORIDE THRESHOLD VALUES FOR REBAR DE-PASSIVATION AND PREDICTION OF DURABILITY LIFE BY SURFACE CHLORIDE ION CONCENTRATION OF REBAR FOR CONCRETE BRIDGE IN MARINE ENVIRONMENT

摘要：

Chloride threshold values are very important regarding to the durability of concrete bridge in marine environment. In this paper the chloride threshold values were determined atatmosphere zone, splash zone and tidal zone respectively at concrete bridges along YanweiOffshore Expressway by detecting and analyzing the indexes related to structure durability,such as chloride ion concentration, thickness of concrete cover, half-cell potential of rebar,electrical resistivity of concrete. Prediction method of durability resisting to chloride ingressis proposed based on the chloride threshold and the chloride ion concentration of rebarsurface.
