Corrosion Inhibiting Admixture – Aqueous Solution
Description
AD-TEK CI is a concrete admixture formulated to give extra service life to concrete structures by protecting the steel reinforcement from corrosion.
AD-TEK CI is a dual action inhibitor, which protects against both anodic and cathodic corrosion.
AD-TEK CI is especially effective against chloride-induced corrosion.
AD-TEK CI exceeds all requirements of Australian Standard 1478.1-2000 as a Special Purpose, Normal Setting Admixture.
Uses
- Bridge decks
- Marine structures
- Parking garages
- Retaining walls
- Industrial plants
- Tunnels
Benefits
- Inhibits both anodic and cathodic corrosion.
- Corrosion inhibition in the presence of varying chloride concentration.
- No changes in concrete mix design required.
- Allows using potential corrosive materials in concrete mix, e.g. beach sand.
- Does not affect the hardened concrete properties.
- Extends the service life of reinforced concrete structures.

Application
AD-TEK CI is best added to the freshly mixed concrete at the batch plant, but may be added to a ready-mix truck at the batch plant or at a building site — the mix water volume being reduced by 50% of the volume of AD-TEK CI added.
AD-TEK CI must never be added to the dry ingredients of a concrete mix. Pre-trial tests are always recommended.
Dosage
Recommended dosage is 2.0–4.0% of cement weight.
Packaging
AD-TEK CI is available in 20-litre and 1000-litre containers, and in bulk.
Storage and Shelf Life
Store at a temperature between 5°C and 40°C. Shelf life in an unopened original container is one year.
