Air entrainment in concrete is the intentional creation of tiny air bubbles in a batch by adding an air entraining agent during mixing. A form of surfactant (a surface-active substance that in the instance reduces the surface tension between water and solids) it allows bubbles of a desired size to form. These are created during concrete mixing (while the slurry is in its liquid state), with most surviving to remain part of it when hardened.

Property Value
dbo:abstract
  • Air entrainment in concrete is the intentional creation of tiny air bubbles in a batch by adding an air entraining agent during mixing. A form of surfactant (a surface-active substance that in the instance reduces the surface tension between water and solids) it allows bubbles of a desired size to form. These are created during concrete mixing (while the slurry is in its liquid state), with most surviving to remain part of it when hardened. Air entrainment makes concrete more workable during placement, and increases its durability when hardened, particularly in climates subject to freeze-thaw cycles. (en)
  • Luftporenbildner sind chemische Substanzen (zumeist Flüssigkeiten), die bei Verwendung im Betonbau im Zementleim viele kleine verteilte Luftporen erzeugen, die auch während des Mischens und Verdichtens stabil bleiben. (de)
  • Un entraîneur d’air est un adjuvant pour matériaux cimentaires tels que les coulis, les mortiers de ciment et les bétons de ciment. Il est utilisé pour protéger ces matériaux contre les cycles de gel/dégel. Les entraîneurs d’air sont ajoutés aux matériaux cimentaires à des ratios entre 0,05 et 0,2 % de la masse de ciment utilisé. La teneur en air dans le matériau durci serait entre 4 et 6 %. (fr)
  • AE제(air entraining agent)는 콘크리트에서 작은 기포를 의도적으로 일괄적으로 생성하는 물질이다. 계면활성제의 일종이며 원하는 크기의 거품들이 형성할 수 있게 한다. 콘크리트 혼합 과정에서 만들어지며, 굳혀질 때 이 중 대부분이 생존한다. 공기 거품의 지름은 보통 10~500 마이크로미터이며 촘촘한 편이다. (ko)
