| Abstract: |
| The effect of exotic environment such as salt solution type and freeze-thaw cycles on chloride diffusion in concreteies was studied by experiment.The effect of salt solution types and freeze-thaw cycles on glectric resistance of concrete and chloride diffusion coefficient were investigated.The result shows that these external environments have effect on chloride diffusion in concrete.The experimental result is analyzed with mechanism of freeze-thaw and theory of diffusion. |
| Key words: salt solution,freeze-thaw cycle,chloride diffusion coefficient,concrete resistance |
