Sika®-CNI (K)

Corrosion inhibiting admixture for concrete

Sika®-CNI (K) is a calcium nitrite based admixture designed to inhibit the corrosion of steel in reinforced concrete. Sika®-CNI (K) contains a minimum of 30 % calcium nitrite by mass. Suitable for use in tropical and hot climatic conditions.

Sika®-CNI (K) is a corrosion-inhibiting admixture that provides protection against corrosion in reinforced concrete structures. Sika®-CNI (K) is recommended for conventional steel reinforcement as well as prestressed or post-tensioned concrete that will be exposed to chlorides from marine environments or deicing salts. Sika®-CNI (K) will extend the service life of structures by effectively inhibiting corrosion in areas such as parking garage decks and support structures, bridge decks, marine structures and many others.
Sika®-CNI (K) may also be used in concrete elements where chlorides are added initially to the concrete mix. Sika®-CNI (K):
  • Extends the service life of reinforced concrete structures.
  • Is recommended for use in all types of reinforced concrete, precast and/or prestressed concrete as well as ready mix applications.
