An experimental study is performed on the impermeability of concrete against chloride ions.Including the portland cement concrete,and the concrete mixed with different mineral admixtures,by use of the ASTM C1202 method,the chloride diffusion coefficient test method called RCM.The correlations between electric flux,Initial current,chloride diffusion coefficient,initial current,Charge and chloride diffusion coefficient were discussed.Tests indicate that,the introduction of mineral admixture can effectively reduce the ability to resist chloride ion penetration into concrete.In a certain age range,it is also showed that initial current,Charge and chloride diffusion coefficient have good correlations between Charge and initial current chloride.
