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