Steel reinforcements of 8 mm diameter and 24 cm length were cut from steel and after pickling
treatment of all specimens. Steel reinforcements then were galvanized by hot dipping method. The
measured coating thickness by thickness gage meter of zinc coat was in the range 8 - 11 μm. Bare
steel samples were also used for comparison reasons. Each steel bar was inserted in a middle of a
plastic tube with 4.5 cm diameter into which concrete was cast. After proper curing, specimens
were immersed into 3.5% NaCl and Dead Sea water separately. Electrochemical impedance spectroscopy
measurements were performed at different time intervals. Results showed that galvanized
steel was corrosion resistant in sea water, and Dead Sea water over the test period.
