On-site determination of corrosion rate in reinforced concrete structures by use of galvanostatic pulses

Galvanostatically induced potential transients can be used to determine the corrosion rate and double layer capacitance (C) of steel in reinforced concrete structures, provided that the steel surface area involved in the measurements is known. An approximate capacitance value, based on previous experience, can also be used to determine polarisation resistance even if the area of the working electrode (WE) is unknown, as in the case of...
