Aug 16, 2021 Concrete Admixtures Air-Entrainment. Air entrained concrete can increase the freeze-thaw durability of concrete. This type of admixture produces a more workable concrete than non-entrained concrete while reducing bleeding and segregation of fresh concrete. Improved resistance of concrete to severe frost action or freezethaw cycles.
