title = "An electrochemical impedance spectroscopy method for identifying the threshold chloride level for rebar in simulated concrete pore solutions",
abstract = "A novel approach was proposed for determining the threshold Chloride Level (CTL) of rebar (HRB400). The Z, which is the resistance value when the frequency is 1 Hz, was extracted from the Electrochemical Impedance Spectroscopy (EIS) data. In a plot of the change in Z1 Hz with [Cl−], the Z1 Hz value was observed to shift sharply when the [Cl−] was at the CTL. The EIS method has a wide application rage and is highly sensitive compared with the potential method and current method. The Simulated concrete Pore Solutions (SPSs) were composed of 0.6 mol/L KOH, 0.2 mol/L NaOH and 0.001 mol/L Ca(OH)2. The carbonation process of concrete was simulated by adjusting the pH value using NaHCO3. The penetration of chloride was simulated by adding NaCl. The influence of the pH on the CTL of HRB400 was significant and non-linear. The temperature had a relatively high impact on the CTL of HRB400.",
