Cuts Rebar Corrosion In
Concrete Repair Projects
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
only one-half hour to several hours after treatment. MCI-2020
is a Migrating Corrosion Inhibitor(tm) that can be sprayed, rolled
on the concrete surface. To be effective, the MCI(r) does not need
to be in contact with the rebar. The MCI(r) inhibitor migrates through
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.
studied as part of the Strategic Highway Research Program (SHRP).
This patented Cortec MCI(r) Inhibitor was found to reduce corrosion
as much as 75%. Cortec MCI(r) was proven effective in both lab and
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
rehabilitation. SHRP projects that the use of MCI-2020 to treat
will increase the life of the bridge 70% longer than polymer modified
an increase of up to 34 years.
