High strength grout with applied nanotechnology for grouting offshore wind turbine installations

SikaGrout^®-9800 is a shrinkage compensated, cement based grout which when mixed with water, produces a homogeneous, flowable and easy pump able grout with exceptional mechanical and physical properties. Latest best binder packing models and applied cementitious nanotechnology produces a grout with superior technical performance and exceptional rheological properties.

C90/105 concrete strength class according EN206 and DIN1045
Can be installed with a continuous mixing and pumping process. Typical output rates of ≥ 20 m³/hour per mixing unit.
Quick return to service and removal of temporary supports due to high early strength build-up. ≥ 40 MPa @ 24hrs at 20°C.
Very good strength gain at low temperatures.
No segregation or bleeding to ensure consistent physical performance inside the grouted connection, and to prevent pump blockages.
Excellent fatigue resistance
No wash-out during below water grouting.
Pump able over long distances and large heights.
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.
Available as silo material.

Usage

SikaGrout^®-9800 has been especially formulated for large scale, pump applications.

Grouting of grouted connections in offshore installations, e.g. foundations of wind turbines or oil & gas installations.
Typical applications are pile-sleeve and stab-in-pile grouted connections, clamp repair, leg filling etc…
Grouting under very harsh conditions, e.g. offshore applications or below water grouting, at temperatures as low as 2°C or up to 42°C.
All void filling from 30 mm to 600mm thickness where high strength is important.
