Formerly: Rheomix 630 S

How does MasterCast 630S work?

MasterCast 630S admixture is a ready-to-use plasticizer for use in no-slump concrete fabrication processes. Formulated to improve the manufacturing efficiency of non-plastic concrete products, this admixture adds a significant degree of cohesion for block and pipe applications. MasterCast 630S admixture improves cement particle wetting and increases strength development as a result.

Recommended uses:

  • Concrete blocks
  • Paving stones and pavers
