MasterRheobuild 1200 - A high range, water-reducing, superplasticising admixture for the production of Rheoplastic concrete

Formerly Rheobuild 1200


The basic components of MasterRheobuild 1200 are synthetic polymers, which allow mixing water to be reduced considerably and concrete strength to be enhanced significantly, particularly at early ages. MasterRheobuild 1200 is a chloride-free product.

Where is MasterRheobuild 1200 applied?

  • Production of rheoplastic self-compacting concrete 
  • Pre-cast concret
  • Low w/c ratio concrete
  • For concrete to be placed in complicated formwork or with congested reinforcement 

What are the advantages of MasterRheobuild 1200?

  • MasterRheobuild 1200 allows the production of very flowable concrete, with a low w/c ratio. 
  • Concrete with MasterRheobuild 1200 shows strengths higher than concrete without admixture having the same workability. 
  • The increase in strength, especially evident at early ages, remains at later ages, both in air-cured and steam-cured processes.
