Ekan® AIR 21

Air Entraining Admixture

  • EKAN®AIR 21 creates permanent microscopic air bubbles within the concrete and mortar.

  • EKAN®AIR 21 also has a plasticizing effect on fresh concrete. It reduces the amount of segregation and even eliminates the problem of bleeding.

  • Using EKAN®AIR 21 minimizes many compatibility issues that can arise between concrete, aggregate, and admixtures.

  • Its highly effective action ensures compatibility with all superplasticizers.
