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. 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.

Application

Application Information

Compatibility

Sika® FerroGard®-901 (IN) is cmpatible with Sika® Products.

Compatible with all types of cements and cementitious materials.

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

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.

 
Consumption

Recommended Dosage

Recommended dosage: 12kg per M³ for any type of concrete

Dosage as per test report of IIT Madras, 1 - 3% by weight of cementitious and W/C should be less than 0.4
