    Crack-reducing concrete admixture

    How does MasterLife CRA 007 work?

    MasterLife CRA 007 admixture is an innovative crack-reducing admixture that is specifically formulated to reduce the magnitude of drying shrinkage and minimize the potential for cracking. Compared to a shrinkage reducing admixture, MasterLife CRA 007 crack-reducing admixture provides enhanced performance through (i) significant reduction in the potential for shrinkage cracking, and (ii) reduced initial crack widths if cracking does occur.

    Recommended uses:

    • Slabs, parking structures, bridge decks, pavements, water-retaining structures
    • Wet-mix shotcrete
    • Mortars and grouts 

    What are the unique features of MasterLife CRA 007?

    • Suitable for use in air-entrained concrete
    • Reduces drying shrinkage
    • Delays time-to-cracking as measured in ASTM C 1581/C 1581M ring test
    • Reduces crack widths

    What are the benefits of MasterLife CRA 007?

    • Enhances watertightness in water-retaining structures
    • Increases concrete durability and service life
    • Reduces joint maintenance costs in concrete slabs
    • Permits increase in joint spacing
    • Reduces the environmental footprint of concrete​
