| description | Disposal of turbine blades exceeding service life has become one of the key issues in green energy and industry. This study investigated the influence of Recycled Turbine Blade Powder (RTBP) and Recycled Turbine Blade Fibres (RTBF) on the workability property, mechanical performance, and environmental impact of mortar incorporating silica fume that could be used in new construction. The experimental program involved the partial replacement of silica sand with RTBP at proportions of 5 %, 10 %, and 15 %. Concurrently, RTBF was incorporated into the mortar matrix at dosages of 2 %, 4 %, and 6 %. The results indicated a linear reduction in workability with increasing RTBP and RTBF content. Mortar mixes containing RTBP and RTBF demonstrated significantly higher mechanical properties, including a 45 % increase in compressive strength, a 25 % rise in tensile strength, and an 80 % rise in flexural strength, compared to the control mix. The fracture energy and stiffness were significantly enhanced with the addition of RTBP and RTBF in the mortar matrix. A comprehensive life cycle evaluation demonstrated 5 % reductions in acidification potential and climate change impact, alongside 10 % decreases across multiple environmental categories, including ionising radiation, land use, resource use (fossil, mineral, and metal), and water consumption. These findings underscore the potential of RTBP and RTBF as sustainable, performance enhancing alternatives in mortar production. |
