Calcium Nitrite

Prouduct Introduction                                 

Calcium Nitrite is widely used as concrete antifreeze, early strength preparation and rust proofing reinforcing bar. The product thoroughly overcomes the limitation of electrochemistry corroding and the alkali aggregate reaction that nitrite appears in the concrete.

​

Application 

Calcium Nitrite liquid is recommended for steel reinforced concrete where longer service lives are desired and it is expected that the concrete will be exposed to environmental chlorides from de-icing salts or massive exposure.

Calcium Nitrite liquid may also be used to offset the potentially corrosive effects of the chloride-bearing concrete-making ingredients and in applications where the initial chloride ion content of the concrete may exceed code requirements or other specified chloride limits.

​

Typical Performance Data                           

The product provides plastic and hardened concrete properties consistent with an ASTM C494 Class C admixture. The extension in service life due to the product is a function of the product dosage, the chloride exposure level, structure design factors and the transport properties of the concrete.  The following tables illustrate the effect of Calcium Nitrite liquid dosage and chloride exposure level:
