MasterRheobuild 858C- A High range, water reducing superplasticizer for rheoplastic concretes

Formerly: Rheobuild 858C

How does MasterRheobuild 858C work?

BASF's MasterRheobuild 858C 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 (25mm) without admixture.

 MasterRheobuild 858C is chloride free.

What are the unique benefits of MasterRheobuild 858C?

The unique benefits of MasterRheobuild 858C are:

  • Reduced thermal peaks
  • High workability for longer periods
  • Lower pumping pressure
  • Delayed setting with longer workability
  • Higher ultimate strengths.
  • Reduced permeability
  • Improved durability

 MasterRheobuild 858C considerably improves the properties of fresh and hardened concrete
