Evaluating the Corrosion Potential and Durability of Reinforced Concrete

Concrete Resistivity Test is a key non-destructive durability test that measures the electrical resistivity of concrete — an important parameter in assessing its ability to resist corrosion. This test helps identify how easily ions, moisture, and chlorides can move through the concrete, making it an essential tool for predicting reinforcement corrosion rate and service life. At Global Lab, we perform the resistivity test using four-probe (Wenner method) and surface resistivity meters, ensuring precise, repeatable, and standard-compliant results for both field and laboratory testing.

Why Concrete resistivityMatters.

Predicts Corrosion Probability

Concrete resistivity is directly linked to the likelihood and rate of steel reinforcement corrosion — a key indicator of durability in chloride or moisture-rich environments.

Evaluates Concrete Quality & Permeability

Higher resistivity means low ion movement and excellent resistance to chloride or carbonation attack, indicating a dense, well-compacted concrete.

Monitors Condition Over Time

Useful for periodic durability assessments — especially in marine, bridge, and industrial structures exposed to aggressive conditions.

Complements Other Corrosion Tests

When combined with Half-Cell Potential and Carbonation Depth Tests, it provides a comprehensive picture of corrosion potential and concrete health.
