CORROSION INHIBITOR
Anti cromozol 95 is a liquid added to concrete during the batching process. It chemically inhibits the corrosive action of chlorides on reinforcing steel and prestressed strands in concrete. DCI S has been formulated to provide set time characteristics similar to untreated concrete at 72°F (22°C).
Facts about Steel Corrosion
Corrosion occurs in the presence of oxygen, moisture, and an electrolyte. As chlorides attack the reinforcing steel, the salt intensifies the electrolyte properties of concrete, thereby creating a corrosion cell. As the corrosion
Reaction occurs, rust is formed. It migrates away from the reinforcing bar, leaving more iron to be
corroded. This process continues and two situations develop:
1. The reinforcing bars disintegrate, which reduces the flexural strength of the concrete structure; and,
2. Iron, as it oxidizes, expands to four times its original volume. This expansion results in physical disruption
of the concrete. Typical results are cracks, stains, crazing, spelling and pot holes; all of which are safety hazards.
DCI S is recommended for all steel-reinforced, post tensioned and prestressed concrete that will come in
contact with chlorides from de-icing salts or a marine environment. Examples are parking garage decks and
support structures, bridge decks and prestressed members, and structures in marine environments. It may
also be used in concrete where chlorides are added during manufacture.
Corrosion Inhibitor is compatible with all types of Portland cements, and concretes containing
pozzolans. However, due to the significant variations between cements, even the same type, differences in
cement response to DCI S may result. This is especially true with respect to the effect on setting time, which
also influences slump retention.
CI is a neutral-set corrosion inhibitor formulated not to affect concrete setting times, which may also aggravate
slump loss. In some cases, environmental conditions may require the addition of an accelerator or
a retarder. In these cases, CI is a non-chloride accelerator, or a retarder such as It may
be added separately to the concrete mix.
CI has now provided an effective and affordable means to increase energy efficiency in pre-existing buildings as well as new construction. CI is working as thermal insulation coatings offer you a way to increase thermal resistance in a clear, coating which is applied like construction. Our award-winning coatings not only reduce energy use, they are also moisture and mold resistant, and low VOC.
CI coatings are naturally resistant to mold growth (without use of moldicides) and therefore will benefit air quality in a building by reducing potential for mold and mildew. Which can be used for encapsulation of dangerous lead-based paint. It is a clear, smooth lead encapsulation coating which can be used over a variety of surfaces. All CI coatings are low VOC and environmentally friendly.
