MCI® - 2020
Tropical Treatment Cuts Rebar Corrosion In Concrete Repair Projects
Cortec's patented MCI-2020 offers a way to dramatically reduce the corrosionof rebar in existing concrete structures. During repair work for bridges,highways, and parking decks, the application of MCI-2020 on concrete can bedone quickly and inexpensively with automobile and pedestrian traffic flowingagain only one-half hour to several hours after treatment. MCI-2020 is a Migrating Corrosion Inhibitor(tm) that can be sprayed, rolled or brushed on the concrete surface. To be effective, the MCI(r) does not need initially to be in contact with the rebar. The MCI(r) inhibitor migrates through concrete in all directions, seeking out all exposed metal areas such as scratches and breaks in the rebar's coating to inhibit further corrosive attackand to neutralize existing corrosion currents.
MCI-2020 was studied as part of the Strategic Highway Research Program (SHRP). This patented Cortec MCI(r) Inhibitor was found to reduce corrosion currents as much as 75%. Cortec MCI(r) was proven effective in both lab and field analysis by SHRP, a unit of the U.S. National Research Council. It found that MCI-2020 was one of the most promising new technologies available for concrete rehabilitation. SHRP projects that the use of MCI-2020 to treat concrete will increase the life of the bridge 70% longer than polymer modified concrete, an increase of up to 34 years.
