An air-entraining admixture which gives concrete extra protection by creating ultra-stable air bubbles that are strong, small and closely spaced - a characteristic especially useful in the types of concrete known for their difficulty to entrain and maintain the air content desired. Even when used at a lower dosage rate than standard air-entraining admixtures.
Features and Benefits
-
The entrainment of optimum air content in concrete results in the following improvements in concrete quality.
-
Increased resistance to damage from freeze/thaw cycles and to scaling from de-icing salts.
-
Reduced permeability - increased water-tightness.
-
Reduced segregation and bleeding.
-
Improved plasticity and workability.
-
Greatly improved stability of air entrainment.
-
Improved air-void system in hardened concrete.
Improved ability to entrain and retain air in low-slump concrete; concrete containing high-carbon content fly ash; concrete containing large amounts of fine materials; concrete using high-alkali cements; high-temperature concrete; and concrete with extended mixing times.
