Use

Sika FerroGard 901 is recommended for all steel reinforced concrete or repair mortars and grouts exposed to corrosive environments. Typical uses are:

• Concrete bridges, highways and pavements exposed to de-icing salts
• Concrete marine structures operating in chloride environments.
• Concrete tunnels, infrastructure or retaining walls.
• Concrete in industrial plants where corrosive substances are present.
• Concrete parking structures and decks.
• Concrete piers, piles, caissons and dock structures.

Sika FerroGard 901 specifically provides protection from chloride and carbonation induced corrosion.

Characteristics and Advantages

• Multifunctional inhibitor, active at both anodic and cathodic sites of a corrosion cell.
• High vapour pressure characteristic of inhibitor results in penetration through concrete.
• High affinity for steel enables displacement of chloride ions from metal surfaces.
• Forms a physical, high integrity and absorbed layer on the surface of embedded steel.
• Continuous barrier protects reinforcement from corrosion caused by loss of alkalinity.
• Creates an environment which restricts influence of moisture and oxygen in concrete.
• Material performance is supported by significant test data and track record.

Sika FerroGard 901 offers owners, specifiers, port authorities, transport ministries and engineers a proven technology in corrosion inhibition that is easily added to ready-mix or precast concrete and repair mortars or grouts. This dual action inhibitor dramatically delays the initiation of corrosion and greatly reduces ongoing corrosion activity.

Sika FerroGard 901:

• Extends the service life of concrete structures and reduces maintenance costs.
• Does not contain calcium nitrite; is non-hazardous and is environmentally friendly.
• Does not affect the rheological properties of plastic concrete; no changes in mix design or placement operations are required.
• Does not affect the properties of hardened concrete such as compressive and flexural strengths, permeability, etc.
• Reduces the harmful effects of steel corrosion which cause concrete cracking, staining, spalling and ultimate loss of structural integrity.
• Provides corrosion inhibition in the presence of chlorides, de-icing and marine salts.
• Enhances the durability of repair mortars and grouts in corrosive environments.

Use

Sika FerroGard 903 is recommended for all steel reinforced, prestressed, precast, posttensioned or marine concrete. Applications include:

• Steel reinforced concrete streets, bridges and highways exposed to corrosive environments (de-icing salts, weathering).
• Steel reinforced concrete in or near a marine environment.
• Parking garage decks.
• Piers, piles, and concrete dock structures.
• As part of Sika’s System approach for building and civil engineering structures.

Characteristics and Advantages

• Sika FerroGard 903 offers owners, port authorities, DOTs, and engineers a new technology in corrosion inhibition that can easily be applied to existing concrete surfaces to extend service life of any reinforced concrete structure.
• Protects against the harmful effects of corrosion by penetrating the surface of even the most dense concrete and migrating to the steel to inhibit corrosion.
• Enhances the durability of reinforced concrete.
• Does not require concrete removal.
• Organic in nature and environmentally friendly.
• Does not contain calcium nitrite.
• Easily applied by either spray or roller to all existing reinforced concrete.
• Can be applied on reinforced concrete that already exhibits some corrosion.
• Adds additional benefits when used prior to protective coatings in concrete restoration systems.
• Water-based for easy handling and application.
• Not a vapour barrier; allows vapour diffusion.
• Aminoalcohols based corrosion inhibitors have proven effective in both laboratory and field analysis as part of the Strategic Highway Research Program (SHRP-S-666).
• ANSI/NSF Standard 61 approved for potable water contact (special order only).

Use

• To mitigate incipient anode formation (halo effect) in patch repair.
• Bridge widening and other structure modifications.
• Slab replacements, expansion joint repairs and other interfaces between new and existing concrete.
• Repair of prestressed and post-tensioned concrete.
• Chloride contaminated or carbonated concrete.
• Repair of structures with epoxy-coated rebar.

Characteristics and Advantages

• Proven technology - Sika Galvashield anodes have an extensive 10+ year track record in the field and have received British Board of Agrément (BBA) approval.
• Type A anode - Alkali-activated to maintain activity of zinc while being noncorrosive to reinforcing steel.
• 2G Technology ^TM- Provides enhanced current output and protection.
• Cast zinc core - Provides high anode utilization in addition to a secure long-term connection between the zinc and the lead wires.
• Integral steel lead wires - Allows for quick and convenient anode installation.
• Provides dependable steel-to-steel contact with no intermediate materials such as galvanizing (which can corrode over time) that may compromise the long-term electrical connection.BarFit^TM design - Grooved edges on Galvashield XP2 and XP4 anodes facilitate the positioning and optimize the contact between the anode and the rebar.
• Economical - Provides localized protection where it is needed the most, at the interface of the repair and the remaining contaminated concrete.
• Versatile - Can be used for both conventionally reinforced and prestressed or posttensioned concrete.
• Low maintenance - Requires no external power source or system monitoring.
• Long lasting - 10 to 20 year service life* reduces the need for future repairs.

*As with all galvanic protection systems, service life and performance is dependent upon a number of factors including reinforcing steel density, concrete conductivity, chloride concentration, humidity and anode spacing.

• Versatile - Effective in chloride-contaminated and carbonated concrete. Can be used for both conventionally reinforced and prestressed or post-tensioned concrete.
• User friendly - Installation is quick and easy.
• Low maintenance - Requires no external power source or system monitoring.
• Measurable - Anode performance can be easily monitored if required.
• Long lasting - 10 to 20 year service life* reduces the need for future repairs.

*As with all galvanic protection systems, service life is dependent upon a number of factors including reinforcing steel density, concrete conductivity, chloride concentration, humidity and anode spacing.
