MasterFlow 9120 - An ultra high strength grout with applied nanotechnology for onshore wind turbine installations


MasterFlow 9210 is a shrinkage compensated, cement based grout which when mixed with water, produces a homogeneous, flowable and pumpable grout with exceptionally high early and final strength. The product exhibits increased ductility, fatigue and impact resistance.

 Latest best binder packing models and applied nanotechnology produces a grout with superior technical performance and exceptional rheological properties.

Where is MasterFlow 9120 applied?

MasterFlow 9210 has been especially formulated for

  • Grouting of onshore wind turbine installations
  • Installations where excellent fatigue resistance is required
  • For filling of voids in precast concrete towers
  • Grouting under very harsh conditions, e.g. temperatures as low as 2°C
  • For application in short weather windows 
  • Anchoring anchor bolts of wind turbine towers
  • All void filling from 20mm to 200mm where high strength, high modulus, high ductility is important

What are the advantages of MasterFlow 9120?

  • Validated according the German DAfStb guideline (RILI): "Production and application of cement based flowing concrete and grouting mortar" (VeBMR)
  • Very high compressive strength: class C80/95
  • Very high modulus for exceptional stiffening properties
  • Excellent fatigue resistance
  • Quick return to service due to high early strength build-up. ≥ 55 MPa @ 24hrs at 20°C
  • No segregation or bleeding to ensure consistent final physical performance and to prevent pump blockages
  • Pumpable over long distances and heights
  • Extended pot life of ≥ 2 hours
  • Specially graded sands and exceptional flow and low friction increases pump output, reduces installation times and costs as well as reducing pump pressures and wear
  • Dust reduced for ease of handling
  • Cement based
  • Low chromate
