TechnoCrete® CIA 30

Bipolar penetrating corrosion-inhibiting admixture for steel reinforced concrete.


TechnoCrete® CIA 30 is a Calcium Nitrite based corrosion inhibiting admixture, designed to inhibit the corrosion of steel reinforcement in concrete which is added to the concrete during the batching process. TechnoCrete® CIA 30 reacts with the reinforcing steel to form a passivating layer of ferric oxide which resists chloride attack and thus increase concrete durability. TechnoCrete® CIA 30 provides nitrite ions to compete with the chloride ions and convert the ferrous oxides into stable ferric oxides, hence protecting the reinforcing steel by delaying the onset of corrosion. TechnoCrete® CIA 30 contains no added chlorides or chemicals known to promote the corrosion of steel.
