Kenneth C. Clear, Inc. has had significant
success in the past seven years using the
three electrode linear polarization (3LP)
technique to define and monitor the rate of
corrosion of steel in concrete.
The technique is based upon the fact that
the D.C current required to alter the natural
electrical half cell potential of the steel
a few millivolts, is proportional to the natural
corrosion rate of that steel.
If a high current is required, the corrosion
rate is high; and vice versa.
The goal of the testing is most often to
predict the future durability and
maintenance requirement of a reinforced
or to define the benefit of a repair
technique as a means of reducing future
expenditures for rehabilitation.
