​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
