New Resipod Concrete Resistivity Meter

Quickly Determine Chloride Ion Penetration
in Concrete

Now you can quickly determine a concrete’s ability to resist chloride ion penetration with the NEW Resipod concrete resistivity meter. The Resipod, in conjunction with a new, about-to-be-released, AASHTO specification, provides the rapid indication of a concrete’s resistance to chloride ion penetration. Applicable to concretes where correlations have been established between this test procedure and long-term chloride bonding procedure, the new test and the Resipod have shown good correlation with chloride exposure tests such as ASTM C1556.

Resistivity Testing Method

The Resipod can determine the electrical resistivity of all types of concrete by providing a rapid indication of its resistance to the penetration of chloride ions. This test method is suitable for evaluation of materials and material proportions for design purposes as well as research and development. Sample age may have significant effects on the test results, depending on the type of concrete and the curing procedure. Most concretes, if properly cured, become progressively and significantly less permeable with time.

DOT Tested and Field Proven

The Resipod was field tested by a number of State Departments of Transportation to ensure its durable design and reliable functionality were field-proven. In a recent test by one State Department of Transportation, the Resipod was able to accomplish in minutes what previously took days using other testing methods. This was a substantial savings in man hours and testing time versus the labor-intensive rapid chloride permeability testing method.

The Measurement Principle

Resipod features a fully integrated 4-point Wenner probe that is designed to measure the electrical resistivity of concrete or rock in a non-destructive test. A current is applied to the two outer probes, with the difference measured by the two inner probes. The typical specimen size ranges from 200 - 300mm (8 - 12 inches) in length and 100 - 150mm (4 - 6 inches) in diameter for cores or cylinders. Other specimen diameters may be tested with appropriate changes to the Wenner probe tip spacing and the correction factor in the calculating equation.
