Air void management

AirVoid Management

A breath of fresh air


Air has a significant impact on the performance of cement and gypsum based building materials and mortars in both positive and negative terms. The manufacturing process of mortars generally requires mixing with water. The application of shear force combined with surfactant components in the mortar mix leads to the distribution and stabilization of air in the fresh mortar.


Air in the right quantity and in the right form is essential for the end properties of mineral-based materials and has a direct impact on the

  • Workability yyMechanical properties

  • Durability

  • Aesthetics

  • Slump properties 

  • Insulation properties 

  • Density

This results, for example, in the formation of a dense structure in self-leveling systems applied in thin layers to floors, while air in renders improves workability and results in a lighter mortar.

Our air entrainers and defoamers can actively control the quantity, the distribution and the size of the air voids
in cement and gypsum based building materials and mortars - we call this AirVoid Management.
