Uses
Sika® FerroGard® -901 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.
Characteristics / Advantages
By using Sika® FerroGard® -901 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 is a combination of organic corrosion inhibitors. The following advantages can be achieved using Sika® FerroGard® -901:
- 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 is neutral to hydrogen embrittlement of prestressed steel i.e. it neither enhances nor limits hydrogen embrittlement of prestressing steel.
