Flange Ring Grouting
BETEC® Early High Strength and Ultra High Strength grouts for flange ring and foundation grouting in steel, concrete and hybrid towers
BETEC® offers grouts in the C80/95 and C110/115 strength classes for wind tower foundation and flange grouting. BETEC® grouts for wind energy are specifically developed to have early high strength, optimised flow and improved de-aeration resulting in an excellent load bearing surface.
BETEC® highly flowable grouts improve job site handling and optimise application time while the fast strength build up allows for construction to continue the same or next day depending on weather conditions. All BETEC® flange grouts are fatigue tested according to Model Code 90, Model Code 2012 and/or EN 1992-2 Part 2. All grouts are subject to a system 2+ factory production control according to EN1504 and Guideline Grouts.

Precast Plant
High performance concrete, quality control and reduction of carbon footprint.
Wind turbine construction continues to increase around the planet, larger structures and harsh exposition conditions require best structure performance and extreme durability. Our extensive portfolio allows for complying with the most ambitious requirements.
Precast elements fabricated with our range of superplasticisers (CHRYSO®Premia or AdvaCast®) answer to requirements such as excellent finishing surface with best placeability and optimum productivity.
Early strengths are granted for element transportation with our CHRYSO®Xel / Daraccel® range of accelerators.
Durability is enhanced with our last generation of fibres and our range of corrosion inhibitors (DCI®). Surface high quality and aesthetics are granted with our complete range of release agents.

Protection
Protecting the structure against corrosion through carbonatation
Carbonation is one of the hazards for concrete structures caused by the ingress of CO2 in combination with humidity reducing the alkalinity of the concrete which can cause reinforcement steel corrosion. To avoid this slumbering threat to the structural integrity of exposed concrete structures, Omnitek® Paint EC can be used on the outside surface. An acrylic flexible painting with a CO2 resistance of 85m Sd, Omnitek® Paint EC, will protect your structure.

- Protection agent: Omnitek® Paint EC RAL 7032 (Other coulours available by request)

Foundations
Improvement of concrete performances and reduction of carbon footprint.
The construction of wind turbine foundations requires large quantities of concrete and steel. However, it is possible to limit the environmental impact and risks associated with these massive concrete elements:
Adfil®STRUX & Adfil®Durus EasyFinish macro-fibres reduce the need for steel reinforcement and therefore carbon weight
CHRYSO ® Cure curing agents reduce the risks for cracking while ECLIPSE® solution reduces the risk for drying shrinkage induced cracking.
EnviroMix® Water reducers allow for the use of low carbon, lower hydration heat and sulfate resistant cements.
Controlling the temperature at the core of the concrete by the use of CHRYSO®Tard retarders preserves concrete durability.
The use of CHRYSO®Optima high water-reducing superplasticisers improves the performance, lifespan and pumpability of concrete while ensuring extended workability retention.
Ensure the control of concrete rheology during mixer truck transit thanks to VERIFI® Technology.

Local Sourcing
Fostering a circular economy through local supply streams.
What if concrete producers could extend the possibilities of sourcing aggregates and sands closer to their production facilities with no compromise on concrete quality?
CHRYSO®Quad water reducers enable the use of challenging aggregates such as high clay contaminated sands, recycled aggregates, coarse sands, 100% manufactured sands’…
This technology offers concrete producers access to local supply streams and fosters circular economy solutions.
