Part of the SikaTop series


Sika FerroGard® 901 Dispersion Liquid

Sika FerroGard 901

is a liquid concrete admixture formulated to protect embedded reinforcing steel from corrosion, and to provide an effective means for extending the service life of concrete structures.

HOW IT WORKS

In sound concrete, steel reinforcement is protected by the highly alkaline environment which deposits a passivating layer of iron oxides around the steel. This passivating layer can be broken down by a number of destructive mechanisms, including carbonation and chloride penetration. Once the steel loses its protective layer, corrosion can begin to occur. Steel corrosion is an electrochemical process consisting of two partial reactions, one at the cathode and one at the anode. Sika FerroGard 901 is an active, dual purpose inhibitor containing a combination of aminoaclohols, and organic and inorganic inhibitors. This protects both the anodic and cathodic parts of the corrosion cell. Due to its high vapor pressure, Sika FerroGard 901 penetrates through concrete to the steel reinforcement, where it is adsorbed onto the surface. Sika FerroGard 901 forms a continuous protective film around the steel presenting a physical barrier to chlorides and other deleterious substances. Because of its high affinity to steel, Sika FerroGard 901 is also able to displace chloride ions from the metal surface to protect concrete from chloride induced corrosion.

APPLICATIONS

Sika FerroGard 901 is recommended for all steel-reinforced concrete exposed to corrosive environments:

  • Steel-reinforced concrete bridges and highways exposed to deicing salts

  • Concrete in or near marine environments

  • Parking garages

  • Piers, piles, and concrete dock structures
