MasterCell 25: Concrete admixture for controlled low strength materials (CLSMs)

Formerly: Rheocell Rheofill

How does MasterCell 25 work?

MasterCell 25 concrete admixture is a ready-to-use, self-contained product for use in various flowable fill applications where reduced densities (unit weights) and air contents of up to 35% are desired.

Recommended uses of MasterCell 25:

  • Backfill (flowable fill) – sewer trenches, utility trenches, bridge abutments, retaining walls, conduit trenches, etc.
  • Structural fill – foundation sub bases, floor slab bases, pipe bedding

What are the unique features of MasterCell 25?

  • Admixture produced CLSM can be used in any application in lieu of compacted soil
  • MasterCell 25 admixture is used in flowable fill mixes to lower the density (unit weight), eliminate settlement, and to control strength development
  • Produces stable air contents of 15-35% and reduces water content by as much as 50%.

What are the benefits of MasterCell 25?

  • Increased yield
  • Optimum workability – can be produced in either fluid or plastic consistency
  • Increased pumpability
  • Little or no bleeding
  • No segregation
  • Reduced shrinkage
  • Reduced settlement
  • Control of strength development
  • Cost-effective compared to in-place cost of compacted soil reactivity
