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
