Abstract

Abstract

The diffusion performance of chloride ion in concrete under the coupling action of dynamic load and environment was researched by a new set of experimental mechanism.The experiment was composed of study on saturated performance of concrete,diffusion performance of chloride ion with different stress levels and under coupling action of dynamic load and temperature.The results showed that the transport mechanism of chloride ion in concrete accounted with diffusion due to the 99% of degree of saturation of concrete;diffusion coefficient of chloride ion was increased with the stress level and temperature increase;and the activation energy for chloride diffusion was 19.9 kJ / mol;life of reinforced concrete bridge was 89.1 years obtained by the model of life prediction of reinforced concrete.
