Sika® FerroGard® CI 222

(former MLife CI 222)

Organic corrosion inhibiting admixture

Sika® FerroGard® CI 222 is an organic migratory corrosion inhibiting admixture formulated to inhibit the corrosion of steel reinforcement in concrete. Sika® FerroGard® CI 222 provides two levels of corrosion protection, inhibiting and waterproofing. Sika® FerroGard® CI 222 functions by inhibiting corrosion at its most critical points. Sika® FerroGard® CI 222 lines the pores of the concrete matrix thus waterproofing and slowing the rate at which chlorides and moisture enter the concrete and denying the corrosion process of its two most important components. Suitable to use in hot and tropical climatic conditions.

Sika® FerroGard® CI 222 increases the life expectency and durability of reinforced concrete by slowing the ingress of chlorides and moisture into the concrete and by forming a strong, durable protective film on the reinforcing steel for a second level of corrosion protection. This protective film slows the corrosion process by preventing chlorides from reacting with the reinforcing steel, and by depriving the corrosion process of moisture and oxygen, thus slowing the rate of corrosion once it begins. This dual mechanism system makes Sika® FerroGard® CI 222 effective with all supplementary cementitious materials, as well as in cracked concrete where the elements that cause corrosion have direct access to the reinforcing steel.

Usage

Sika® FerroGard® CI 222 typical uses: 
  • 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.

Technical Information

Concreting guidance

The standard rules of good concreting practice for production and placing must be observed when using Sika® FerroGard® CI 222 in concrete. Refer to relevant standards.
Fresh concrete must be cured properly especially at high temperatures in order to prevent plastic and drying shrinkage. Use Sika® Antisol® products as a curing agent or apply wet hessian.

Application

Application Information

Dispensing

Sika® FerroGard® CI 222 may be added with concrete batch water. It should not be mixed with any other admixtures prior to being introduced into the concrete mixer. The use of this admixture does not require changes in normal batching procedures.

Compatibility

Sika® FerroGard® CI 222 is suitable for mixes containing all types of cement and supplementary cementitious materials such as Microsilica (Silica Fume), Fly Ash (PFA), GGBS (ground granulated blast furnace slag) and the following Sika products:
SikaPlast®, Sika® ViscoCrete®, Sikament®, Plastiment®, SikaPump®, SikaFume®, SikaFiber®, Sika® Aer, Sika® Stabilizer, SikaControl®
We recommend to perform trial mixes to establish the required performance when combining Sika® FerroGard® CI 222 with the above products or other admixtures. Please consult our Sika Technical Department.
Consumption

Recommended dosage

5 L/m³ of concrete for all applications and corrosion environments.
Sika® FerroGard® CI 222 dosed at 5 L/m³ is formulated to provide optimum corrosion protection of reinforced concrete structures in severe corrosive environments and therefore provides excellent corrosive protection in less severe corrosion environments as well.
Sika® FerroGard® CI 222 is formulated for use at a single dosage in order to eliminate the confusion and uncertainties related to determining the severity of the corrosive environment and predicting the chloride exposure of the structure.
