    ​MasterPolyheed 8861 - New generation mid-range water reducer

    How does MasterPolyheed work?

    MalsterPoyheed 8861 is a multi-component, non-chloride, mid-range water reducing admixture designed to improve the performance of concrete both in the pastic and hardened states. It is a versatile admixture able to produce mid-range slumps without retardation. Its formulation contains materials able to improve the conrete's rheology, strength and finishability.

    What are the recommended uses of MasterPolyheed 8861?

    • All types of concrete where a non-chloride water reducing admixture is required, especially in the slump band (80-150mm)
    • Improving the performance of pumped concretem shotcrete and conventionally placed concrete
    • Ready mixed concrete using manufactured sands
    • Long-distance transporting
    • Pumped concrete
    • High workability without segregation or bleeding
    • High performance concrete for durability

    Whare are the features and benefits of MasterPolyheed 8861?

    • Good dispension in mixes with high manufactured sand contents
    • High workability for longer periods
    • Lower pumping pressure with manufactured sands
    • Resistance to segregation even at high workability
    • Extended setting with longer workability
    • Reduced water content for a given workability
    • Higher ultimate strengths
    • Increased ease in finishing concrete with poor aggregates/gap graded aggregates

    Chemistry and mechanism of action is what differentiates MasterPolyheed 8861 from the traditional admixtures, being a new, unique mechanism of action that greatly improves the effectiveness of cement dispension coupled with rheology improvement.
