MasterRheobuild 857AD - A high range, water reducing superplasticiser for concretes containing GGBS and microsilica
Formerly: RHEOBUILD 857AD
How does MasterRheobuild 857AD work?
MasterRheobuild 857AD 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 (25 mm) without admixture. MasterRheobuild 857AD is chloride free
What is MasterRheobuild 857AD used for?
- Mixes containing GGBS or microsilica
- Mass concrete pours
- Ready mixed concrete
- Pumped concrete
- Casting in hot climates
- High workability for longer periods
- Lower pumping pressure
- Delayed setting with longer workability
- Higher ultimate strengths.
- Reduced permeability
- Improved durability
What are the advantages of MasterRheobuild 857AD?
MasterRheobuild 857AD considerably improves the properties of fresh and hardened concrete.
