Sikament® RB 808 (formerly known as MasterRheobuild® 808) - Optimised superplasticing admixture for producing rheoplastic concrete.

How does MasterRheobuild 808 work?

MasterRheobuild 808 is a ready to use, liquid admixture designed to produce high slump concrete. Rheoplastic concrete is typically fluid concrete with a slump value of ≥200mm that flows easily but at the same time is free from segregation. MasterRheobuild 808 contains no added chloride and meets the requirements of ASTM C494 Type A and F admixtures.  

Recommended uses:

• Use with all cements and admixtures meeting international specifications.
• Pre-cast and ready-mixed concrete
• Pumped concrete

What are the features and benefits of MasterRheobuild 808?

• High workability for shorter placement time.
• High water reduction to produce high impermeability and strength leading to improves durability.
• Superior cohesion with no segregation even at high workability. Excellent concrete quality.
• High early strength for early de-moulding.
• Low shrinkage and creep for better dimensional stability
