MasterRheobuild 857Q- A High range, water reducing superplasticiser for concrete including mixes containing GGBS and microsilica

Formerly: Rheobuild 857Q

How does MasterRheobuild 857Q work?

BASF's MasterRheobuild 857Q is formulated from synthetic polymers specially designed to impart rheoplastic qualities to concrete, particularly those containing GGBS or microsilica. A rheoplastic concrete is a fluid concrete with a slump of at least 200 mm, easily flowing, but at the same time free from segregation and having the same water/cement ratio as that of a low slump concrete (25mm) without admixture.

MasterRheobuild 857Q is chloride free.

What are the unique benefits of MasterRheobuild 857Q?

The unique benefits of MasterRheobuild 857Q are:

  • High workability for longer periods
  • Lower pumping pressure
  • Delayed setting with longer workability
  • Higher ultimate strengths.
  • Reduced permeability
  • Improved durability

MasterRheobuild 857Q considerably improves the properties of fresh and hardened concrete
