Description

An ultra-high performance grout specifically designed for structural grouted connections for onshore wind turbine foundations, non-structural offshore foundation connections and segmental concrete wind towers.

Advantages:

  • Non-shrink.
  • High flexural strength and modulus of elasticity without the addition of fibres, enhancing the flow characteristics of the grout.
  • Quick return to service and removal of temporary supports due to high early strength build-up, even at low temperatures.
  • High fatigue resistance.
  • Suitable for pumping or pouring over a large range of applications.
  • No segregation or bleeding to ensure consistent final physical performance and to prevent pump blockages.
