Sika® FerroGard®-901 (IN)
Corrosion inhibiting concrete admixture
DESCRIPTION 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. USES Sika® FerroGard®-901 (IN) 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 (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.

BASIS OF PRODUCT DATA
All technical data stated in this Product Data Sheet are based on laboratory tests. Actual measured data may vary due to circumstances beyond our control. FURTHER DOCUMENTS If frozen Sika® FerroGard®-901 (IN) may be used again after slow thawing at room temperature and intensive stirring. ECOLOGY, HEALTH AND SAFETY For information and advice on the safe handling, storage and disposal of chemical products, users shall refer to the most recent Material Safety Data Sheet containing physical, ecological, toxicological and other safety-related data.
APPLICATION INSTRUCTIONS 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.
