AB The development of more sustainable materials for the constructionsector begins with optimal use of natural resources and appropriately recyclingthe residues produced at the end of the lifecycle of infrastructures. In the comingyears, many wind-farms will be dismantled, providing big amounts of waste windturbine blade (WWTB). This waste can be an opportunity to decarbonize theconstruction industry, which causes huge green-house-gas emissions each yearendangering the environment.Waste generated during the demolition of concrete elements has been used inthe past few years for structural concrete manufacturing in the form of RecycledConcrete Aggregate (RCA). Feasibility of combination of RCA with WWTB hasyet to be study in concrete mixtures.This study aims to analyze the simultaneous use of RCA and WWTB toproduce a greener concrete mixture as an effort to transform an industry hithertoconsidered polluting into a more sustainable one. For this purpose, three concretemixtures were produced with different volume combinations of each waste: 0%WWTB and 0% RCA; 5% WWTB and 50% RCA; and 10% WWTB and 100%RCA. Compressive strength, modulus of elasticity and Poisson´s coefficient haveall been evaluated at 28 days. Results show that an adequate dosage of both types ofresidues can result in a structural concrete mixture that preserves basic compressivestrength properties while at the same time providing an outlet for a large amountof waste generated in both construction and wind energy sector.
