AB Many of the first wind-turbine installations are reaching the end of their useful life, so their blades have to bereplaced. Inexpensive, sustainable, and straightforward recycling solutions are therefore needed. The conversionof turbine blades into raw materials for concrete solutions is proposed in this paper, through a novel recyclingprocess entailing non-selective cutting, crushing, and sieving of the blade walls, without component separation.The material, Raw-Crushed Wind-Turbine Blade (RCWTB), consists of fiberglass-composite fibers, polyurethane,and balsa-wood particles. It serves as concrete fibers and aggregates, according to its physical and microscopiccharacterizations. A customized concrete mix design and a five-stage mixing procedure with up to 6% RCWTBachieved suitable workability levels. The compressive strength of the RCWTB concrete was 40 MPa, and it had ahigher load-bearing capacity and a lower carbon footprint than ordinary concrete. The results encourageresearch on the overall performance of RCWTB concretes.
