Use: 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.
Packing: 25/40kg woven bag lined with plastic or according tocustomer requirements.
