What are Air-Entraining Concrete Admixtures?
Air-entraining concrete admixtures facilitate the development of a system of microscopic air bubbles within concrete during mixing. The main reason for the use of air-entraining admixtures is to increase the resistance of concrete against the alternating freezing and thawing cycles of water. TCC Materials carries multiple air-entraining products such as Akona Liquid Air Entraining Admixture and Tenon Air Entrainment. Both products are ready-to-use, aqueous solutions made of organic materials. The products entrain a small and stable amount of air into the desired mix.
These small, stable air voids enhance the mixture and improve workability. Its chemical composition and physical properties make it ideal for many construction applications. It is intended for use when increased workability and freeze-thaw durability of concrete or mortar is preferred. These admixtures also improve resistance to freeze/thaw, scaling, segregation, and bleeding and improve the strength, plasticity, water retention, and cohesiveness of mortar. Meets ASTM C260 Standard Specification for Air-Entraining Admixtures for Concrete.
