Abstract

Electrochemical Impedance Spectroscopy (EIS) has been used to monitor at the same time the curing process of cement bentonite mixture and the iron corrosion rate in this mixture. It has been shown that the curing process has extended over a period of at least 100 days at room temperature. During this period, the iron corrosion rate was always low i.e. about 2 nm/year in aerated condition and about 1 nm/year in anaerobic condition. These values have confirmed that such cement bentonite mixture was an efficient environment to avoid iron corrosion damages even in aerated condition.
