Sika® FerroGard®-901 (IN)

Corrosion inhibiting concrete admixture

Sika® FerroGard®-901 (IN) is a Bipolar corrosion inhibiting liquid concrete admixture based on Sika® FerroGard® Technology for use in reinforced concrete and mortar. It acts as a corrosion inhibitor for the steel reinforcement. By using Sika® FerroGard®-901 (IN), the life expectancy and durability will be substantially increased.

By using Sika® FerroGard®-901 (IN) both the anodic and cathodic reactions of the electrochemical corrosion process are reduced. The product forms a film on the steel surface which delays the onset of corrosion and also reduces the rate of corrosion. Sika® FerroGard®-901 (IN) is a combination of organic corrosion inhibitors. The following advantages can be achieved using Sika® FerroGard®-901 (IN):
  • Corrosion protection for embedded reinforcing steel, especially from chloride attack
  • Protection from the destructive influences of reinforcement corrosion
  • No negative influences on the properties of both the fresh and the hardened concrete
Sika® FerroGard®-901 (IN) is neutral to hydrogen embrittlement of prestressed steel i.e. it neither enhances nor limits hydrogen embrittlement of prestressing steel.

Technical Information

Concreting Guidance

The standard rules of good concreting practice, concerning production and placing, are to be followed.

Laboratory trials shall be carried out before concreting on site, especially when using a new mix design or producing new concrete components.

Fresh concrete must be cured properly and curing applied as early as possible.

Application

Application Information

Compatibility

Compatible with all types of cements and cementitious materials.

Important: Always conduct trials before combining products in specific mixes and combinations.

Restrictions

Sika® FerroGard®-901 (IN) shall not be added to dry cement.

DISPENSING

Sika® FerroGard®-901 (IN) is mixed with the gauging water or added at the same time into the concrete mixer. It may also be added to the concrete in the transit mixer at the point of discharge. In this case, an additional mixing time of at least 1 minute per m3 concrete must be observed. Before discharging it, check the concrete visually for uniform consistency.

The quantity of Sika® FerroGard®-901 (IN) in the mix design should be taken into consideration when determining the quantity of water for a specific W/C ratio.

Sika® FerroGard®-901 (IN) is not to be mixed with dry cement.
