Abstract: abstract:In this study the electrochemical technique is applied to accelerate chloride ion migration in concrete to determine the chloride ions in anode cell, and the pore characteristic of the same mortars in concrete was obtained from the mercury intrusion porosimetry (MIP). The plain ordinary Portland cement and the constant aggregate with eight w/c ratios ranging from 0.3 to 0.65 were used. A good linear relationship between the steady-state migration coefficient and non-steady-state migration coefficient based on the same experimental setup and specimens was obtained. Both of the steady-state migration coefficient and non-steady-state migration coefficient were linearly related to the capillary pore volume and the critical pore diameter.
