Calcium nitrite can be used as the raw material for making the antifreeze of concrete and anticorrosive of reinforcing.
It overcomes the disadvantages of alkali aggregate reaction and electrochemical corrosion caused by the sodium Nitrite in the concrete, and improves the performances of concrete in the physical mechanics and endurance, and makes it possible to obtain the excellent concrete .It is a new type of reinforcing bar anticorrosive and antifreeze free from chlorine and alkali aggregate. It has the inaction and protection effect for reinforcing bar, its performance of anticorrosive is better than that of sodium nitrite.
Liquids calcium nitrite is in buckets of 200kg(net weight) or Flexitank (23.4MT).
Powder calcium nitrite is in bags of 25kg, 950kg (net weight).
Store in a cool, ventilated warehouse. Keep away from fire and heat.
Storage areas should be equipped with suitable materials to contain leaks.
