Wind power plants of UHPC 2.2 : An investigation of high-performance concrete with synthetic fibre reinforcement STRUX (English)
Abstract [sv]

Användandet av betong som ersättare för stål vid produktionen av vindkraftverkstorn har ökat den senaste tiden. Betongtorn är betydligt billigare än ståltorn men problem som sprickbildningar, frostsprängningar och följaktligen armeringskorrosion har uppstått bl a på grund av vibrationer från rotorn. I fundamentet i vindkraftverk kan ovan nämnda problem också uppstå och det uppfyller således inte alltid funktionskraven. Det här examensarbetet undersöker möjligheten att eliminera dessa problem genom att använda en sorts högpresterande betong kallad UHPC 2.2 med syntetfiberarmeringen, STRUX. Jämförelser mellan tidigare empiri om högpresterande betong och laborativa tester på UHPC 2.2 visar att den senare är beständigare och ger möjligheter till en större sprickfrihet. Sammanfattningsvis har den högpresterande betongen med fiberarmeringen STRUX visat sig vara en konkurrenskraftig möjlighet på marknaden.

Abstract [en]

The use of concrete has recently increased as a replacement to steel for the construction of towers for wind power plants. However there are problems such as cracking or frost scaling and finally corrosion of reinforcement, partly due to vibrations caused by the power plants' blades. In the foundation of power plants, the above problems also occur and do not always fulfill the functional requirements. This thesis investigates the possibility to eliminate these problems by using a special kind of high-performance concrete called UHPC 2.2 with synthetic fiber reinforcement, STRUX. When comparing previous empirics about regular concrete with laboratory tests on this high-performance concrete, we find that the later is more durable. In summary, the high-performance concrete with fiber reinforcement STRUX is shown to be a competitive market opportunity.
