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


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
