- Improves the durability of concrete against frost and severe weathering conditions.
- Significantly improves the cohesion of concrete mixes.
- Improves workability.
Cemairin 280 is an air-entraining admixture for concrete, formulated from selective polymers to create highly stable microscopic air bubbles which distribute uniformly in the concrete mix.
This effect can be used to improve the resistance of concrete mixes against freezing and thawing, severe weathering and de-icing compounds.
