Management of wind-turbine blade waste as high-content concrete addition: Mechanical performance evaluation and life cycle assessment.

The management of end-of-life wind-turbine blades in the coming years will be necessary, as a clear solution for their recycling is yet to be found due to their complex composition. The suitability of their mechanical recycling is therefore evaluated in this paper, obtaining Raw-Crushed Wind-Turbine Blade (RCWTB) for subsequent incorporation in high amounts of up to 10% vol. in concrete, replacing the aggregates to achieve Fiber-Reinforced Concrete (FRC).

Effects of temperature and moisture fluctuations for suitable use of raw-crushed wind-turbine blade in concrete.

Raw-crushed wind-turbine blade (RCWTB), a waste from the recycling of wind-turbine blades, is used as a raw material in concrete in this research. It contains not only fiberglass-composite fibers that bridge the cementitious matrix but also polyurethane and balsa-wood particles. Therefore, concrete containing RCWTB can be notably affected by moisture and temperature fluctuations and by exposure to high temperatures.
