UHPC materials are used in all processes of alternative and active native energy production used as the material for foundations, as a lining-material for protection against corrosion, wear and as a construction material. Due to the diverse application possibilities and the superior properties compared to standard concrete qualities, UHPC are increasingly used in the mentioned areas. UHPC has the advantage that it can be processed just like standard concretes.Hydroelectric power plants or storage power plants
Due to the extreme corrosion resistance of UHPC concrete constructions with a much higher reinforcement density per volume can be used. This can significantly increase the strength of the construction or the wall thicknesses or layer thicknesses can be reduced while maintaining strength.
In the right combination UHPC is very resistant to wear and cavitation.
Since UHPC already reaches 70% of its maximum nominal strength in the standard quality after 48 hours and in the special quality after only 12 hours.
UHPC is available as mortar, casting material and shotcrete material.
Tidal power plants
Some tidal power plant systems are already being used in Europe and Asia. There are now a lot of technical variations of tidal power plants for the coasts but also for directly in the sea. One thing all needs a stable seawater resistant and durable foundation.
Based on the experience gained with the foundation systems of the offshore wind power plants, high quality UHPC materials are ideally suited for this purpose. In particular, the enormous adhesive power of UHPC in anchoring and bolt system is required here. What is once shed in a UHPC foundation can no longer be removed from the foundation, even with enormous forces. Not only in this regard, UHPC is many times superior to normal standard concrete.

Biogas power plant
Biogas has been produced in many small plants in the past. There are already very large production facilities in Europe. The plants have corrosion and wear problems due to the production process. Especially wherever standard concrete was used. Here, a UHPC protective layer of a few millimeters can be used to achieve permanent corrosion protection. To achieve a very long service life, UHPC concrete should be used for the new construction.
We have some repair projects on floodgates, dams and water barriers, UHPC concretes can also be used for this work? As you describe, you use UHPC material in both seawater and freshwater areas. In our repair area we see many corrosion problems on concrete and steel structures. The repair work that has been done so far has not been very sustainable and needs to be repeated regularly.
ReplyDeleteIn the last twenty years, some locks, dams and weir for flood control and altering river conditions and jetty projects have been carried out on Europe's coasts. In most cases it was about wear and corrosion repairs. Here we have always been able to rely on our experience in the offshore sector successfully, especially as far as the installation methods above as well as underwater are concerned. In some areas, complete steel structures have been replaced by UHPC designs.
