Description SikaFerroGard-901 is a high-performance, corrosion-inhibiting liquid specifically designed for the protection and maintenance of reinforced concrete structures. It is a penetrating, silicate-based solution that helps protect steel reinforcement from corrosion by migrating into the concrete and forming a protective layer on the surface of the steel. SikaFerroGard-901 is formulated to work effectively in both new and existing concrete structures, offering long-term corrosion protection. Uses Sika Ferrogard-901 is specifically formulated to protect reinforced concrete at risk of corrosion, particularly from chloride-induced damage. Typical applications include: Concrete roads Bridges Tunnels Retaining walls Industrial plants Multi-story car parks Advantages By using Sika Ferrogard®-901, both anodic and cathodic reactions of the electrochemical corrosion process are reduced. The product forms a protective film on the steel reinforcement, slowing the onset of corrosion and decreasing its rate. Sika Ferrogard®-901 combines organic corrosion inhibitors, offering the following benefits: Effective corrosion protection for embedded reinforcing steel, particularly from chloride exposure Guards against the harmful effects of reinforcement corrosion Does not negatively affect the properties of fresh or hardened concrete Neutral to hydrogen embrittlement of prestressed steel, meaning it neither promotes nor mitigates hydrogen embrittlement of prestressed steel Technical Data Base: Organic and inorganic nitrogen-containing substances Appearance/Color: Green liquid Density: 1.06 kg/L pH Value: 10 ± 1 Packaging: Available in 5 kg and 20 kg pails, and 200 kg drums (bulk tank options available upon request) Storage Conditions/Shelf Life: 12 months from the production date, when stored properly in sealed, undamaged containers, at temperatures between 1°C and 35°C, away from direct sunlight and frost. Application Recommended Dosage: 12 kg per cubic meter of concrete Addition: Sika Ferrogard®-901 is added to the gauging water or directly into the concrete mixer. It can also be introduced into the transit mixer at the point of discharge, with at least 1 minute of additional mixing per cubic meter of concrete. Ensure the concrete has a uniform consistency before discharging. The dosage of Sika Ferrogard®-901 should be considered when adjusting the water content for the desired water/cement (W/C) ratio. Concrete Placing: Sika Ferrogard®-901 typically produces high-quality concrete. Standard best practices for concrete manufacturing and placement must be followed, including proper curing of the concrete. Compatibility: Sika Ferrogard®-901 can be combined with the following Sika® products: Sikament® superplasticizers Sika Fro®-V5-A Silica fume-based products from the Sikacrete®/Sikafume® range Sika Retarder® and Sika Retardol®-25 It is always recommended to conduct pre-trials with these combinations to ensure the desired performance and application characteristics. Important Notes Frozen Sika Ferrogard®-901 can be reused after slowly thawing it at room temperature and stirring thoroughly. All technical data provided is based on laboratory tests. Actual results may vary depending on site-specific conditions.
