Sika® FerroGard®-901 S

Corrosion inhibiting concrete admixture

Sika® FerroGard®-901 S is a 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 S, the life expectancy and durability of reinforced concrete can be substantially increased.

By using Sika® FerroGard®-901 S both the anodic and cathodic reactions of the electrochemical corrosion process are reduced. The product forms a protective layer on the steel surface which delays the onset of corrosion and also reduces the corrosion rate. Sika® FerroGard®-901 S is a combination of organic corrosion inhibitors. The following advantages can be achieved using Sika® FerroGard®-901 S:
  • 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 S is neutral to hydrogen embrittlement of prestressed steel i.e. it neither enhances nor limits hydrogen embrittlement of prestressing steel.
