Influence of Ferronickel Slag on Impermeability of Seawater-Corroded Cement Soil Using an Electrochemical Test

Table 6

The evaluation criteria for the corrosion status of steel bars.

No.	Potential status of steel bars (mV)	Judgment of steel corrosion status
1	< –350	There is a 95% probability that the steel bar is corroded or highly corroded.
2	–200 to –350	There is a 50% probability that the steel bar is corroded, and there may be pitting.
3	0 to –200	The probability of rusting is 5%; there is no rust, or the rust status is uncertain.
