AB Many wind-turbine blades are approaching the end of their operational life, and they mustbe replaced soon. As a result, there is a pressing need for cost-effective, sustainable, and simplerecycling methods. This paper proposes a recycling process that transforms turbine blades into rawmaterials for concrete production. Raw-crushed wind-turbine blade (RCWTB) obtained from dismissedwind-turbine blades was incorporated in mixes containing recycled aggregates to improve fresh andearly-age mechanical properties. The RCWTB is composed of glass fibers, polymeric particles, and balsawood; based on its physical and microscopic properties, it works as both concrete fibers and aggregates.As a key finding, incorporating this waste material was observed to improve the early-age properties ofconcrete containing recycled aggregates. Plastic shrinkage decreased up to 47% and flexural strengthreached 14% higher values, while compressive strength remained almost unchanged.
