Incorporating these materials into concrete enhances sustainability and, in some cases, improves mechanical properties while reducing the final environmental impact and cost compared to conventional concrete. A comprehensive characterization of the mechanical properties of concrete mixtures with varying RCA (0–100%) and RCWTB (0–10%) contents was conducted, these mixes being designed with increased water and admixture contents to compensate for the expected loss of workability caused by the addition of these waste materials. A Life-Cycle Assessment (LCA) and cost evaluation were also performed. The optimization of these mixtures was addressed using the Response Surface Method (RSM). The optimization process revealed that intermediate combinations of RCA (50%) and RCWTB (5%) yielded maximum flexural-tensile properties. However, achieving optimal performance proved more challenging when simultaneous optimization included compressive strength and deformability properties, such as modulus of elasticity and Poisson’s coefficient. For these properties, the optimal mix incorporated 88% RCA and 0% RCWTB. The RSM analysis demonstrated the feasibility of incorporating both RCA and RCWTB into concrete mixtures, mainly intended to work under bending stresses, but it also highlighted the complexities of achieving optimal performance when all mechanical properties were simultaneously considered. This research underscores the potential for these recycled materials to contribute to more sustainable concrete production while addressing the trade-offs in mechanical performance optimization. application/pdf eng Elsevier Cleaner Materials. 2025, V. 16, p. 100317 https://doi.org/10.1016/j.clema.2025.100317 Atribución-NoComercial 4.0 Internacional http://creativecommons.org/licenses/by-nc/4.0/ info:eu-repo/semantics/openAccess Recycled Concrete Aggregate Raw-crushed wind-turbine blades Concrete Response surface method Mechanical performance Global warming potential Cost Materiales de construcción Hormigón-Ensayos Ingeniería civil Building materials Concrete-Testing Civil engineering Optimization of concrete containing wind-turbine wastes following mechanical, environmental and economic indicators info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Cleaner Materials 16 100317 THUMBNAIL Hurtado-cm_2025.pdf.jpg Hurtado-cm_2025.pdf.jpg IM Thumbnail image/jpeg 4909 https://riubu.ubu.es/bitstream/10259/10479/4/Hurtado-cm_2025.pdf.jpg 5c39eaf1f0a5ab8feeb73e5160a4b6db MD5 4 LICENSE license.txt license.txt text/plain; charset=utf-8 1362 https://riubu.ubu.es/bitstream/10259/10479/3/license.txt 5d013bfa6e473ff0db22cd82a4d71a70 MD5 3 CC-LICENSE license_rdf license_rdf application/rdf+xml; charset=utf-8 914 https://riubu.ubu.es/bitstream/10259/10479/2/license_rdf 24013099e9e6abb1575dc6ce0855efd5 MD5 2 ORIGINAL Hurtado-cm_2025.pdf Hurtado-cm_2025.pdf application/pdf 7989540 https://riubu.ubu.es/bitstream/10259/10479/1/Hurtado-cm_2025.pdf d5e95c5af27c52ff1984d5da5a4c7507 MD5 1 10259/10479 oai:riubu.ubu.es:10259/10479 2025-05-17 02:05:10.019 Repositorio Institucional de la Universidad de Burgos bubrep@ubu.es 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
