In the context of the global push towards renewable energy sources such as wind power, the sustainable management of the end-of-life wind turbines becomes crucial. The decommissioning of wind farms generates a significant amount of wastes, particularly from wind turbine bladesWind turbine blade and concreteConcrete footings. In this context, the combined use of residues from crushed wind blades and recycled aggregateRecycled concrete aggregate from their foundations is studied to evaluate their suitability for concreteConcrete production. The study explores different mixes of these materials in low-strength concreteConcrete with a target compressive strength of 25 MPa. The impact of incorporating varying proportions of these recycled materials on the mechanical propertiesMechanical properties of the concreteConcrete is analyzed. The findings indicate that while the wind blades residue slightly reduced the compressive strength, it significantly enhanced the flexural strength. The results demonstrate that the combined use of both residues offers a viable option for concreteConcrete applications requiring high bending strength. This study suggests the potential for effectively incorporating these wind turbines by-products into construction materials.
