2004-3-28  The MCI products have successfully inhibited corrosion of the rebar in a 3.5% NaCl solution for duration of testing. MCI protected samples showed an average corrosion rate of 0.34 µA/cm2 compared to untreated samples that were 1.50 µA/cm2. This will increase the life expectancy by more than 15 years.
