    ​MasterRoc HR 603

    High-Range Water-Reducing Admixture

    How does MasterRoc HR 603 work?

    MasterRoc HR 603 ready-to-use high-range water reducing admixture is based on the new generation of polycarboxylate technology that incorporates state-of-the-art molecular engineering to provide fast wet-out of powder materials. MasterRoc HR 603 admixture is effective in improving the production efficiency of a concrete plant by rapidly dispersing powder materials in concrete mixtures, thereby minimizing mixing time. It is formulated to meet ASTMC 494 requirements for Type A, water-reducing, and Type F, high-range waterreducing, admixtures.

    Recommended uses:

    • Concrete applications requiring high-early compressive strength development
    • Concrete mixtures with low w/cm and/or high powder contents
    • Concrete with varying water reduction requirements
    • Self-consolidating concrete (SCC)

    What are the unique features of MasterRoc HR 603?

    • Dosage flexibility
    • Rapid cement dispersion
    • Superior early and ultimate strengths

    What are the benefits of MasterRoc HR 603?

    • Optimized mixture costs
    • Shorter mixing time in central mixers
    • Increased productivity
    • Greater batch-to-batch consistency​
