| Abstract: |
| A new electrochemical method has been proposed to determine the diffusion coefficient of Cl~-in hardened cement paste.Diffusion of Cl~-is caused by the concentration gradient of Cl~-in pore solution which results from a reversible redox reaction involving Cl~-.Diffusion coefficient of Cl~-is determined by the transition time in chronopotentiometric method. |
| Key words: hardened cement paste,diffusion coefficient of Cl~-,chronopotentiometry |
