Sulfate Ions

The effect of sulfate ions on the corrosion behavior of steel in ordinary Portland concrete (OPC) and high performance concrete (HPC) were investigated. Steel corrosion was evaluated by means of corrosion potential (Ecorr), linear polarization resistance (LPR), electrochemical impedance spectroscopy (EIS) and cyclic polarization (CP). The electrochemical results indicated that, compared to the pure chloride solution, the presence of sulfate ions in the chloride solution both reduced the time to corrosion initiation and lead to an increase in corrosion rate of steel in OPC specimens; however, the sulfate ions had negligible effect in HPC specimens. Furthermore, the corrosion rate of steel exposed to chloride solution was higher that to the sulfate solution both in OPC and HPC specimens.

Corrosion behaviors of Q235 steel in simulate ammonium sulfate solution were studied. Effects of the ammonium sulfate concentration, Cl- concentration, pH and the flow velocity on corrosion of Q235 steel in simulate ammonium sulfate solution were investigated by the weight-loss method, and the electrode processes were studied by polarization curves. The result showed that: (1) the corrosion rate of Q235 steel increased with the increase of Cl- concentration firstly. When Cl- concentration was 10000ppm, the corrosion rate reached the maximum value of 6.698 mm/a, and then, with the increase of Cl- concentration, the corrosion rate decreased. (2)With pH increasing, the corrosion rate of Q235 steel decreased. (3)The corrosion rate increased with the increase of the concentration of ammonium sulfate firstly. When the concentration of ammonium sulfate was 5%, the corrosion rate reached the maximum value of 5.462 mm/a. And then the corrosion rate decreased. (4)The influence of the flow velocity on Q235 steel corrosion was remarkable, with the increase of the flow velocity, the corrosion rate increased rapidly.
