    ​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 c​oncrete
    • 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 water tightness​
    • Improved plasticity and workability
    • Reduced segregation and bleeding
    • Increased freeze / thaw resistance
    • Increased resistance to scaling
    • Greatly improved stability of air entrainment
