MasterRheobuild 875 - A high range, water-reducing, superplasticising admixture for the production of rheoplastic concrete

Formerly Rheobuild 875


The basic components of MasterRheobuild 875 are synthetic polymers, which allow mixing water to be reduced considerably and concrete strength to be enhanced significantly, particularly at early ages. 

MasterRheobuild 875 is a chloride-free product.

Where is MasterRheobuild 875 applied?

  • Production of rheoplastic self-compacting concrete 
  • Pre-cast concrete 
  • Low w/c ratio concrete 
  • In complicated formwork or with congested reinforcement 

What are the advantages of MasterRheobuild 875?

  • MasterRheobuild 875 allows the production of very flowable concrete, with a low w/c ratio. 
  • Concrete with MasterRheobuild 875 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. 
  • Initial and final sets do not change significantly with respect to concrete without admixture.
