DCI-S

DCI-S corrosion inhibitor chemically inhibits the corrosive action of Chlorides on reinforcing steel and  prestressed strands in concrete. It has been formulated to provide set time characteristics similar to untreated concrete at 22°C. DCI-S is a liquid added to concrete during the batching process. DCI-S corrosion inhibitor is a system containing Calcium Nitrite which interacts with the embedded steel in concrete to prevent salt attack.

By chemically reacting with the reinforcing, a barrier is formed which prevents chloride penetration. Corrosion initiation is delayed and corrosion rates are kept under control. Once corrosion has been inhibited, physical disruption of the concrete due to rust  formation will not occur. When added to concrete in sufficient quantity as determined by the  anticipated chloride ion content of the concrete over the design life of the structure, DCI-S maintains an active corrosion-controlling system within the concrete matrix. DCI-S complies with AS 1478.1-2000, Type SN.
