Resistivity of Concrete


Resistivity of concrete is the method for measuring the flow of electrical currents that may have opposing materials within concrete or rock. By accurately measuring the flow of electricity, Resistivity testing detects the possibility of reinforcing steel corrosion and the diffusion rates of chloride within the concrete. Knowing more about the condition of the surface strength will enable better project efficiency by evaluating the time needed to allow for: fresh concrete setting, concrete curing, crack detections, measuring the transfer of moisture, corrosion of rebar and early compressive strength.

Humboldt offers several tools to accurately measure the electrical resistivity in concrete and rock. All tools measure the concrete with non-destructive testing. Check out The Resipod Resistivity Meter, Giatec Surf™ Surface Resistivity and the Giatec RCON2™ Concrete Resistivity. If you have questions or need help selecting equipment, please call us at 1.800.544.7220 or use our Ask Humboldt form.
