Calcium Nitrite

Product Description

Calcium nitrite, is an inorganic compound, chemical formula Ca(NO2)2, widely used in reinforced concrete engineering, mainly used as cement hardening accelerator and anti-freeze rust agent.

Application

Calcium nitrite is mainly used as the main raw material of cement concrete admixture, and can be configured as concrete antifreeze, steel rust inhibitor, early strength agent, etc. This product can also be used in heavy oil washing, lubricating oil emulsification and chemical organic synthesis and other fields.

1, antifreeze: can reduce the freezing point of the mixed concrete, the construction temperature can reach a minimum of -25°C under negative temperature conditions, can promote the hydration reaction of mineral components in cement, is a new generation of chlorine-free low alkali antifreeze.

2, steel rust inhibitor: steel has excellent passivation rust and protection effect, adding 2-3% calcium nitrite in concrete can extend the life of buildings and structures by 20-50 years

3, can be configured compound early strength agent; Improve the strength of concrete, reduce the amount of cement, shorten the construction period.

Calcium nitrite can fundamentally overcome the defects of alkali aggregate reaction and electrochemical corrosion in concrete, improve the physical and mechanical properties and durability of concrete, and obtain high-quality concrete.
