Surface Resistivity Test

What is a Surface Resistivity Test

The Surface Resistivity (SR) Test is a non-destructive, electrically-based method for estimating hardened concrete permeability. This test method is currently recommended for approving concrete mixture designs when the concrete is to be placed in environments prone to promote corrosion of embedded steel reinforcement. It is a proven and mature test method which can replace the more laborious determination methods which have been the standards for many years.

Benefits

Use of the Surface Resistivity Test in lieu of older testing methods saves technician labor and may also reduce the time required to approve concrete mixture designs. The SR Test requires approximately 10 minutes of technician time to perform, and it can be performed on cylindrical test specimens prior to their use for compression testing. Other methods of testing require dedicated test specimens and at least 24 hours of technician labor.
