Sikament® RB 845 (formerly known as MasterRheobuild® 845) - High range, water reducing and superplasticizing admixture for concrete
How does MasterRheobuild 845 work?
MasterRheobuild 845 is formulated from synthetic polymers specially designed to impart rheoplastic qualities to concrete, particularly those containing Fly Ash, GGBS or Microsilica. A rheoplastic concrete is a fluid concrete with a slump of at least 200mm, easily flowing, but at the same time free from segregation.
MasterRheobuild 845 is chloride free.
What are the unique benefits of MasterRheobuild 845?
The unique benefits of MasterRheobuild 845 are:
- High workability for longer periods
- Lower pumping pressure
- Delayed setting with longer workability
- Higher ultimate strengths.
- Reduced permeability
- Improved durability
MasterRheobuild 845 considerably improves the properties of fresh and hardened concrete
