AIR-ENTRAINING AGENT
Entraîneur d’air
Materials
An admixture that forms air bubbles in concrete
or mortar. Air-entraining agents increase the
plasticity of the concrete as well as the frost
strength after hardening, improve tightness, and
retard excessive drying in summer and
segregation during transportation. Their main
disavantage is that they reduce the strength of the
mortar or concrete.
