The POTENTIAL WHEEL
& DATABUCKET (PW & DB) is a portable system for the rapid
assessment of the likelihood of corrosion of steel reinforcement
within concrete. Anodic and cathodic areas of the reinforcement
are detected by changes in voltage that they produce. The PW &
DB is used to measure these voltages and produce a map of those
areas with the potential to corrode.
APPLICATIONS
Specifically for evaluation the corrosion
potential of steel reinforcement in concrete.Probable corrosion rates can be estimated with the addition
of resistivity measurements using the RESISTIVITY METER.
STANDARDS
Conforms to ASTM C876; standard test method
for half cell potentials of uncoated reinforcing steel in concrete.
