Cold Weather Concrete Additives
MNC-C is a new generation of chloride-free anti-freezing admixture mainly compounded by naphthalene based superplasticizer with minor nitrate and sulfate. Thus it has anti-freezing, early strengthening, air-entraining, and water-reducing effect for concrete in very cold conditions, It’s used to reduce the time that concrete must be protected against freezing in ambient temperatures ranging from -10 degree C to -25 degree C.
MNC-C series are suitable for the construction of common concrete, pumping concrete, large volume concrete, and ready mixed concrete in cold weather.
Features & Benefits
- High water reducing effect.
- Completely water soluble and low alkali content, apparent reducing effect on the alkali-aggregate reaction.
- Improved concrete workability, pumpability and early strength.
- Low dosage.
