Product Description:

Calcium Nitrite for Cement Concrete Admixtures

Molecular formula: Ca(NO2)2

Molecular weight: 132


Calcium ammonium nitrate is white or grey granular which dissolves in water absolutely.

It is a new type high-efficient compound fertilizer.Suitable both for straight application and blending.

Property and main advantage:

It contains nitrogen and calcium,and also supplies nitrogen to plant quickly, nitric nitrogen not needed to be transferred.

It is a neutral fertilizer and can improve the quality of soil.

It can lengthen the florescence,promote the root,stem,leaf to grow normally.

Ensuring the color of the fruit is bright and the fruit candy can be increased.

Technical standard: Q142401/CSC-01-2000

This product is mainly used as main raw material of cementconcrete admixture and can be

prepared to concrete antifreeze, rebar corrosioninhibitor, early strength agent, etc. This product can

also be used in heavyoil washing, lubricating oil emulsification, chemical organic synthesis andother


1. Antifreeze: Can reduce the freezing point of themixing concrete. Construction temperature can be

down to -25 °C. Negativetemperature can promote the hydration of mineral components in cement. It is a new generation of low-alkali chlorine-free antifreeze.

    2. Rebar corrosion inhibitor: It has excellentpassivation, rust resistance and protection effects.

Adding 2-3% calciumnitrite can prolong the life of buildings and structures for 20-50 years.

    3. Can prepare early strength agent to improve concretestrength, reduce cement consumption and

shorten construction period.

    This product fundamentally overcomes the defects ofconcrete alkali aggregate reaction and

electrochemical corrosion, improves thephysical and mechanical properties and durability of concrete

to get highquality concrete.
