MasterRheobuild SP11 - High range water reducing, superplasticizer for rheoplastic concretes

How does MasterRheobuild SP11 work?

MasterRheobuild SP11 is composed of synthetic polymers specially designed to impart rheoplastic qualities to concrete.

A rheoplastic concrete is a fluid concrete with a slump of at least 200 mm, easily flowing, but at the same time free from segregation and having the same water/cement ratio as that of a no-slump concrete (25 mm) with admixture.

MasterRheobuild SP11 is chloride free.

Recommended uses:

  • Pre-cast Concrete
  • Site mixed concrete
  • Pumped concrete
  • Wet Shotcrete Mixes
  • Concrete containing Slag/ Pozzolans
  • Mass concrete
  • Concreting in low temperatures

What makes MasterRheobuild SP11 a unique solution?

MasterRheobuild SP1 is for < M-40 grade concrete with high early strength, mainly for Precast Concrete.

What are the features and benefits of MasterRheobuild SP11?

  • Reduced water content for a given workability
  • Minimal bleed water
  • High early strengths – quicker de-stripping
  • Lower pumping pressure
  • Increased ease in finishing concrete
  • Increased compressive, tensile and flexural strengths as a benefit of its water reducing action
  • Reduced permeability - Improved durability
  • Reduced thermal peaks – reduced cracking
  • Reduced shrinkage and creep
  • Provides lower in-place cost
