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 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.
