About Steel-Reinforced concrete
Steel-reinforced concrete is literally responsible for every city skyline in existence, but chlorides in the environment will eventually corrode and degrade the steel inside it. This causes the steel rebar or mesh inside concrete to corrode, severely diminishing the strength of a concrete structure. Before the steel corrodes, however, it also expands up to four times, causing cracks, stains, crazing and spalling.
What is DCI®?
DCI® is a corrosion inhibitor containing calcium nitrite, which deposits on the reinforcing steel to create a chemical barrier. This barrier delays the onset of corrosion, and prevents corrosion from accelerating once it starts. In sufficient quantity, DCI® will maintain an active corrosion-controlling system within the concrete matrix throughout the lifetime of the structure.
Why choose DCI® corrosion inhibitors?
A category creator at launch, DCI® is now the most validated corrosion inhibiting admixture in use. We offer reams of advice and support on the correct way to add DCI® or DCI® S to a concrete mix. In project after project, DCI® has been shown to work exactly as intended, protecting from corrosion and extending the service life of structures around the world. For more information on how to add DCI® or DCI® S to a building project, contact Chryso today.

Products
DCI® N
DCI® N is a corrosion-inhibiting admixture specifically formulated to chemically inhibit the corrosive action of chlorides on reinforcing steel and prestressed strands in concrete while maintaining the equivalent plastic and hardened properties of untreated concrete.
DCI-S
DCI-S is a corrosion-inhibiting admixture designed to chemically inhibit the corrosive action of chlorides on reinforcing steel and prestressed strands in concrete, helping to delay corrosion initiation and maintain long-term corrosion protection.
