Impede® CNI

Impede® CNI is a ready to use aqueous solution of 30% calcium nitrite which chemically inhibits corrosion of steel embedded in concrete. Impede® CNI is recommended for corrosion protection of steel reinforced post tensioned strands and pre-stressed strands embedded in concrete which is exposed to chlorides. Typical applications include concrete structures built in cold climates where de-icing salts are used (such as bridge decks and parking structures), and marine environments (such as bridges, piers, docks, and sea walls).
