PolyЯRon CI

Description

PolyЯRon CI is a calcium nitrite liquid corrosion inhibiting admixture for concrete containing steel reinforcement PolyЯRon CI admixture chemically retards the onset of corrosion action of chlorides on reinforcing steel and will increase a structure’s service years.

Advantages

• Extends the service years of reinforced concrete.
• Provides effective corrosion protection to the reinforcing steel in the concrete from the presence of chlorides (de-icing salts).
• Offsets the corrosive effects of concrete ingredients that have exceeded normal chloride limits (admixed chlorides).
• In cold weather, concrete setting times and strength development are accelerated without the incorporation and added cost of a non-chloride accelerator.
• Aids in prevention of concrete from freezing at higher dosages.

Application area

PolyЯRon CI is an effective corrosion inhibitor for all types of steel reinforced concrete. PolyЯRon CI is recommended for use in post-tensioned, precast, and prestressed concrete applications. Also, it is recommended for use in parking garages, marine structures, bridge decks, and any other project that requires corrosion protection from de-icing salts or chloride exposure

Dosage

PolyЯRon CI is recommended for use at a dose of 10 to 30.0 L/cubic meter of concrete. The dosage will depend on the anticipated chloride loading of the structure and how severe the corrosive environment is. Calcium nitrite must be dosed in quantities equal to or greater than the chlorides for the entire life of the structure. This requires dosing calcium nitrite in accordance with the anticipated chloride exposure of the concrete.
