MasterRheobuild 1100 PX - A high range water reducing superplasticiser admixture for the production of high slump concrete. Supplied as a powder.

Formerly Rheobuild 1100 PX


The basic component of MasterRheobuild 1100 PX powder is synthetic polymers. These polymers will allow mixing water to be reduced considerably and concrete strength to be enhanced significantly, particularly at early ages. MasterRheobuild 1100 PX powder is a chloride free product.

Where is MasterRheobuild 1100 PX applied?

  • Production of high slump concrete 
  • Precast concrete
  • Low water cement ratio concrete
  • In complicated formwork or with congested reinforcement 
  • Improving strengths in manufactured concrete products 
  • Re-tempering of concrete at site

What are the advantages of MasterRheobuild 1100 PX?

MasterRheobuild 1100 PX liquid allows the production of high slump flowable concrete, with a low water/cement ratio. 

Concrete with MasterRheobuild 1100 PX liquid 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. 

Therefore whenever longer transport and finishing times are needed the use of a retarding BASF superplasticiser, or the use of MasterRheobuild 1100 PX liquid in conjunction with MasterRocĀ® HCA 10 should be considered.
