    MasterRheobuild 1000

    High-range water-reducing admixture

    Formerly: Rheobuild 1000

    How does MasterRheobuild 1000 work?

    MasterRheobuild 1000 high-range, water-reducing admixture is formulated to produce rheoplastic concrete. Rheoplastic concrete flows easily, maintaining high plasticity for time periods longer than conventional super-plasticized concrete. Rheoplastic concrete has the low water-cementitious materials ratio of no-slump concrete, providing excellent engineering (hardened) properties. The slump-retention characteristics of rheoplastic concrete permit the addition of MasterRheobuild 1000 admixture at the batch plant. MasterRheobuild 1000 admixture meets ASTM C 494/C 494M requirements for Type A, water-reducing, and Type F, high-range water-reducing, admixtures.

    Recommended uses:

    • Concrete where high plasticity, normal-setting characteristics and accelerated strengths are desired
    • Prestressed, precast and ready-mixed concrete applications
    • Civil and mining applications

    What are the unique features of MasterRheobuild 1000?

    Plastic State:

    • Range of 8-11 in. (200-280 mm)
    • Extended slump retention
    • Controlled set times
    • Cohesive and non-segregating
    • Minimal bleed water
    • Hardened State
    • Higher earlier strengths than can be achieved with conventional high-range water reducers
    • Increased ultimate compressive strength
    • Higher modulus of elasticity
    • Improved bond strength to steel
    • Low permeability
    • High durability
    • Reduced shrinkage and creep
    • Highly reliable in-place structural integrity

    What are the benefits of MasterRheobuild 1000?

    • Less dependence on consolidation energy
    • Job time and cost reduced through higher productivity rates and/or reduced labor
    • Early strength allows for accelerated construction methods, resulting in completion dates ahead of schedule
    • Engineering specification changes can allow for greater limits on the free-fall of concrete, lift heights, concrete temperatures and potential economic mixture adjustments
