- True
- False
Show hintHide hint
Think about how electrical potential relates to corrosion risk.
Question 5.
You are given a concrete sample tested by ASTM C1202 with a result of 3500 coulombs. Analyze the implications for this structure's long-term performance in a coastal environment.
Show hintHide hint
Consider how environmental conditions interact with results.
Question 6.
A reinforced concrete beam showed a half-cell potential reading of -500 mV consistently over time. What steps would you recommend to mitigate the risks of corrosion?
Show hintHide hint
Determine preventative measures based on the readings.
