Description 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. Uses Sika® FerroGard®-901 S is designed for reinforced concrete particularly at risk of corrosion. It specifically provides protection from chloride-induced corrosion. Typical uses are in: Concrete roads Bridges Tunnels Retaining walls Industrial plants Multi storey car parks Benefits 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.
