MCI 2020 is
organic, surface applied, migrating corrosion inhibitor designed to penetrate through cementitious
materials including concrete, mortar, and limestone. It migrates in both liquid
and vapor (gas) phases through the pore structure, forming a protective,
molecular layer on embedded reinforcement and allowing vapor diffusion. MCI®2020
provides strong corrosion protection against carbonation, chlorides, and other
contaminants and will migrate independent of orientation (horizontal, vertical
or overhead up to 8 cm (3 inches) in 30 days.
Water based, non-flammable
MCI 2020 offers engineers, owners, contractors, DOTs, and other government
agencies a time proven, corrosion inhibiting technology that will significantly
extend the service life of their reinforced concrete structures. MCI®
2020 can be applied to new concrete or used for rehabilitation and will not
delay construction or increase costs. Unlike standard inorganic inhibitors it
does not have to come in contact with the reinforcing steel upon application. MCI®2020
is considered ambiodic (mixed) which means it protects both anodic and cathodic
areas within a corrosion cell. It contains
a synergistic blend of amino-alcohols and salts of carboxylic acids which form
a protective layer on embedded reinforcement delaying the onset of corrosion as
well as reducing existing corrosion rates.
MCI 2020 is recommended for: preventative
maintenance of existing reinforced, precast, prestressed, post-tensioned, or
marine concrete structures , bridges, highways, and industrial floors exposed
to aggressive environments (chemicals, deicing salts, carbonation, atmospheric
attack), parking garages, concrete piers, dams, offshore platforms, piles,
pillars, pipes, utility poles, cooling towers and concrete potable water
is also an important component of Cortec’s High Performance Repair System™
MCI 2020 is easily
applied by spray, brush, or roller and does not etch, stain, discolor, or
otherwise harm glass, metals, or automotive paint. It does not contain calcium
nitrite or wax and no removal of sound concrete is required. It’s excellent performance
is proven in both lab and field testing.
MCI 2020 conforms to
ASTM G 109, ASTM E 96,
meets ANSI/NSF Standard 61 Approval for structures containing potable water and
is RoHS compliant.
embedded reinforcing steel was causing spalling on the walls of Pentagon.
Carbonation on the walls lowered the pH of the concrete causing the corrosion.
The requirements included: a minimum 20 year design life, stop water
absorption, reduce or stop corrosion, and maintain the appearance of the walls.
The repair program consisted of 18600 m2 (200,000 ft2) of
surface hand patch repair and over 92903 m2
treated with MCI® 2020 V/O, and a silicate based coating. MCI®
2020 V/O was chosen to protect and repair the walls based on its warranty and
its fulfillment of the other specified repair design requirements. MCI®
2020 enabled Pentagon building premium repair, rehabilitation, and protection
for the next 50 years.
