MasterRheobuild 845- A high range, water reducing and superplasticizing admixture for concrete

How does MasterRheobuild 845 work?

BASF's MasterRheobuild 845 is formulated from synthetic polymers specially designed to impart rheoplastic qualities to concrete, particularly those containing Fly Ash, GGBS or Microsilica. A rheoplastic concrete is a fluid concrete with a slump of at least 200mm, easily flowing, but at the same time free from segregation.

 MasterRheobuild 845 is chloride free.

  • High workability for longer periods
  • Lower pumping pressure
