MasterRheobuild 522 - Retarding Superplasticising admixture for concrete


How does MasterRheobuild 522 work?

MasterRheobuild 522 superplasticising admixture is composed of synthetic polymers specially designed to impart rheoplastic qualities to concrete.
Recommended uses of MasterRheobuild retarding superplasticising admixture is:

  • Ready mixed concrete
  • Long hauls
  • Pumped concrete
  • Concrete containing Granulated Slag/ Pozzolans
  • Mass concrete pours
  • Hot weather concreting

What makes MasterRheobuild 522 a unique solution?

MasterRheobuild 522 is for < M-40 grade concrete with longer workability retention, mainly for ready-mixed concrete.

What are the features and benefits of MasterRheobuild 522?

  • Reduced thermal peaks
