5 Quality Control Applications
The Resipod model with 38 mm spacing conforms to the AASHTO T 358 Surface Re-
sistivity Test Method which uses surface resistivity as an indication of the perme-
ability of concrete . Details of the test can be found on the official AASHTO website:
http://tig .transportation .org/Pages/SurfaceResistivityTest .aspx
The Resipod family is completed by two further instruments differentiated by application as can
be seen in the table:

Resistivity
Surface resistivity test on standard cylinders (4” x 8”, 100 x
200mm) or (6” x 12”, 150 x 300mm) with a maximum aggre-
gate size (1 .5”, 38mm) . Fixed probe spacing (1 .5”, 38mm)
Bulk resistivity test on cylinders up to 100mm (4”) diameter
Surface resistivity test on non-standard cylinders with ag-
gregate sizes that may exceed > 1 .5”, 38mm
Correction factor for probe spacing
Correction factor for sample geometry
User definable correction factor
Variable probe spacing
Surface resistivity mapping on site for: estimation of likeli-
hood of corrosion, corrosion rate and implementation of
cathodic protection systems
5.1 Resipod Bulk Resistivity
The accessory comprises of a stand that allows the instrument to be conveniently mounted, cables
that are easily inserted into the rear connectors and the measurement plates with conductive foam
inserts suitable for 4”x8” cylinders .
The stand accommodates both Resipod versions (38 mm and 50 mm) .
