| Abstract Scope |
In the context of the global push towards clean energy sources, the sustainable management of end-of-life wind turbines becomes crucial. The decommissioning of wind farms generates significant waste, particularly from wind turbine blades and concrete footings. The combined use of residues from crushed wind blades and recycled aggregate from their foundations was studied to evaluate their suitability for concrete production. The study explored their application in low-strength concrete, with a target compressive strength of 25 MPa, incorporating varying proportions of the recycled materials. The findings indicate that while the residue from wind blades slightly reduced the compressive strength and stiffness, it significantly enhanced the flexural strength. Additionally, the use of these residues lowered both the embodied carbon and cost of the concrete, making it a viable option for applications requiring high bending strength. This study suggests the potential for effectively utilizing these wind turbine by-products in construction materials. |
