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 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 857AD?

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