MasterAir 200

Air Entraining Admixture for Concrete

TS EN 934-2: T5

Material Description

MasterAir 200, is an air-entraining admixture which gives concrete extra protection by creating ultrastable
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.

MasterAir 200 Areas of Application

• Concrete exposed to freeze/thaw attack.

• To reduce bleeding due to poor aggregate grading.

Characteristics 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 deicing salts.

• Reduced permeability - increased watertightness.

• Reduced segregation and bleeding.

• Improved plasticity and workability.
