MasterRheobuild 857AE - A high range, water reducing superplasticiser for concretes containing GGBS and microsilica

How does MasterRheobuild 857AE work?

MasterRheobuild 857AE 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 857AE is chloride free 

What is MasterRheobuild 857AE used for?

  • Mixes containing GGBS or microsilica 
  • Mass concrete pours 
  • Ready mixed concrete 
  • Pumped concrete 
  • Casting in hot climates

To obtain: 

  • 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 857AE?

MasterRheobuild 857AE considerably improves the properties of fresh and hardened concrete.
