MasterRheobuild 890 - A high range, water-reducing superplasticiser for rheoplastic concretes
Formerly Rheobuild 890
MasterRheobuild 890 is formulated from synthetic polymers specially designed to impart rheoplastic qualities to concrete.
A rheoplastic concrete is a fluid concrete with a slump of at least 200mm, easily flowing, but at the same time free from segregation and having the same w/c ratio as that of a low slump concrete (25mm) without admixture.
MasterRheobuild 890 is chloride-free.
Where is MasterRheobuild 890 applied?
- Microsilica concrete
- Mass concrete pours
- Ready-mixed concrete
- Long-distance transport
- Pumped concrete
- Casting in hot climates
What are the advantages of MasterRheobuild 890?
- Reduced thermal peaks
- High workability for longer periods
- Lower pumping pressure
- Delayed setting with longer workability
- Higher ultimate strengths
- Reduced permeability
- Improved durability
