Dosage
Usage Guideline
Corrosion-Inhibiting System: In order to control corrosion in reinforced concrete, the ACI 318 (ACI 318M) Building Code Requirements for Structural Concrete and Commentary requires certain design considerations, such as limiting the water-cementitious materials ratio, providing adequate concrete cover over reinforcing steel and limiting the initial chloride ion content of the concrete. Additionally, construction practices should be such that a dense, void-free concrete is
obtained.
In addition to the elements of good concrete practice required by the ACI 318 (ACI 318M), RXSOL recommends a corrosion-inhibiting system that inhibits corrosion at multiple levels for maximum protection. The use of MasterLife RXSOL CIA 222 admixture restricts the ingress of chlorides and moisture and additionally slows the onset and rate of corrosion by forming a protective film on the reinforcing steel. Additional protection can be attained through the use of a high-range water-reducing admixture such as RXSOL admixture to provide adequate placability and consolidation at low water-cementitious materials ratios and/or the use of silica fume to further reduce concrete permeability.
Dosage:
RXSOL CIA 222 admixture is recommended for use at a dosage of 1 gal/yd3 (5 L/m3) of concrete for all applications and corrosive environments. RXSOL CIA 222 admixture dosed at 1 gal/yd3 (5 L/m3) is formulated to provide optimum corrosion protection of reinforced concrete structures in severe corrosive environments, and, therefore provides excellent corrosion protection in less severe corrosion environments as well. RXSOL CIA 222 admixture is recommended for use at a single dosage in order to eliminate the confusion and uncertainties related to determining the severity of a corrosive environment and predicting the chloride exposure of the structure. Mixing: RXSOL CIA 222 admixture may be added with concrete batch water. It should not be mixed with any other admixtures prior to being introduced into the concrete mixer. Depending on local materials, mixing efficiency and other conditions, the use of this admixture may require changes in normal batching procedures to facilitate air entrainment.
