Superplasticizer for Cold Weather
PC-C15
(-10 degree C to -25 degree C)
Description
PC-C15 is a polycarboxylate based superplasticizer of antifreeze type, which could be applied under minus 10-25 degrees.
Application
PC-C15 series are suitable for construction of common concrete, pumping concrete, large volume concrete and ready mixed concrete in cold weather.
Features & Benefits
1. High water reducing effect.
2. Completely water soluble and low alkali content, apparent reducing effect on the alkali-aggregate reaction.
3. Improved concrete workability, pumpability and early strength.
4. Low dosage.
