The instrumentation comprised EG&G Model 273 Potentiostat/Galvanostat
with IR compensation option,a computer,and a printer.A stainless
steel frame was used as counter electrode.Fig.2 is a schematic representation
of the test setup.The potential scan was applied at an incremental
rate of 0.2 mV/sec in the range (E .- 250 mV) to (E .+ 250 mV).IR
drops between the reference and the working electrode (steel embedded in
concrete) are automatically compensated for by the system using current-interrupt technique.
