The measurement of the electrical resistivity of cement-based materials, e.g., concrete, is used for quality control and durability assessment. In an existing structure, the electrical resistivity of the concrete can be monitored using either pre- or post-embedded probes. When using post-embedded probes, the contact material (grout) used when installing the probe can affect the measurements. This work investigated the effect on the measurement of two different grouts (in alkaline and carbonated condition) used for the installation of a post-embedded probe in carbonated mortar. The effect of the geometry of the system was also examined.
