Abstract

Abstract

Prism concrete specimens,with a W/C of 0.55,were immersed in chloride solutions under and after axial compressive stress.Chloride ions contents were obtained from the stressed specimens after 180 d exposure.Results showed that chloride ions content kept nearly the same in specimens with different compressive stresses below 70% of strength for loading and loaded specimens.This value increased significantly when concrete was loaded to 95% stress and then unloaded.Chloride ions diffusion coefficient decreased firstly when the stress was below 70% of strength,and then gradually increased.Chloride ions diffusion coefficient in loaded concrete was slightly large than that in loading concrete with the same compressive stress below 70% of strength.The chloride content and diffusion coefficient were also larger for perpendicular direction than that along the loading direction.Polynomial equations were established according to the experiment results for durability design of actual structures.
