Half Cell Potential Testing

Half Cell Potential Testing is a non-destructive electrochemical method used to evaluate the likelihood of corrosion in steel reinforcement within reinforced concrete structures. The test measures the electrical potential difference between the embedded steel and a reference electrode placed on the concrete surface, indicating areas at risk of corrosion activity.

Applications of Half Cell Potential Testing:

• Assessing corrosion activity in bridges, buildings, chimneys, silos, and pavements
• Condition assessment of reinforced concrete in power plants, oil & gas facilities, and industrial structures
• Mapping corrosion-prone areas for targeted repair and rehabilitation
• Evaluating the effectiveness of corrosion inhibitors and protective coatings
• Quality control in construction and long-term durability studies

Method Used: A reference electrode (commonly copper-copper sulfate or silver-silver chloride) is placed on the concrete surface, and a voltmeter is used to measure potential differences. Readings are interpreted as per ASTM C876 to assess corrosion risk levels.
