​MasterAir 720 - Air-entraining admixture for concrete

 

How does MasterAir 720 work?

MasterAir 720 is an air-entraining admixture which creates ultra-stable air bubbles that are strong, small and closely spaced.

Recommended uses:

Entraining controlled air content in a wide range of concrete types:

  • Low slump concrete
  • Flowable concrete
  • High temperature concrete
  • Concrete with extended working times
  • Lightweight and pre-stressed concrete
  • Imparting workability to lean harsh mixes
  • Reducing bleeding caused by grading deficiencies in the concrete materials

What makes MasterAir 720 a unique solution?

MasterAir 720 helps to produce light weight, low density concrete with freeze and thaw resistance.​

What are the features and benefits of MasterAir 720?

The use of MasterAir 720 to entrain optimum air content in concrete results in the following improvements in concrete quality:

  • Improved ability to entrain and retain air in concrete
  • Improved air-void system in harden concrete
  • Reduced permeability – increased watertightness
  • Improved plasticity and workability
  • Reduced segregation and bleeding
  • Increased freeze / thaw resistance
  • Increased resistance to scaling
  • Greatly improved stability of air entrainment
