New use of recycled windmill rotor blades as aggregate for UHPC concrete

UHPC grouting material is used worldwide in the

in the offshore and onshore industry worldwide for more than 25 years. 

Mostly, UHPC Grout has been used to make transition pieces and foundation systems for wind energy, oil production, tidal power plants and floating windmill platforms. There are also plans to use UHPC concrete as corrosion protection for the systems in these areas. It would be a safe, easy to install, cost effective and durable solution. Another development for the future is the combination of UHPC concrete and recycled rotor blade material. Several thousand used rotor blades from offshore and onshore wind turbines are lying on the ground around the world to be recycled or disposed of. Storage has become a very big problem in some countries. In many industrial
applications we use glassglass fibres, carbon fibres or plastic fibres asaggregates to our UHPC concrete. 

 

In order to carry out reuse, recycling and upcycling as standard in the near future, special UHPC concretes are the ideal combination partner. It should also be possible to add construction material from wind turbines to our UHPC with appropriate processing. This could then possibly be used again as foundation material for new onshore or offshore wind turbine.
