Retired fan blade powder-fiber 3D printing concrete and preparation method thereof

The invention discloses retired fan blade powder-fiber 3D printing concrete and a preparation method thereof.The retired fan blade powder-fiber 3D printing concrete is prepared from a solid component and water, and the mass of the water accounts for 16%-19% of the mass of the solid component; the solid component comprises the following components in percentage by mass: 28%-32% of a cementing material, 8%-12% of fan blade powder, 2.5%-7.5% of fan blade fibers, 52.5%-57.5% of fine sand and 0.163%-0.225% of an additive, and the fan blade powder and the fan blade fibers are both prepared from the retired fan blade. While waste utilization is realized, the concrete added with the retired fan blade is excellent in performance and suitable for being used in the building industry. 本申请公开了一种退役风机叶片粉末-纤维3D打印混凝土及其制备方法，包括固体组分和水，水的质量为固体组分质量的16％-19％，固体组分包括以下质量百分比的组分：胶凝材料28％-32％、风机叶片粉末8％-12％、风机叶片纤维2.5％-7.5％、细砂52.5％-57.5％以及外加剂0.163％-0.225％，所述风机叶片粉末和风机叶片纤维均采用退役风机叶片制备而成，本申请将退役风机叶片应用在混凝土中，实现废物利用的同时，加入退役风机叶片的混凝土性能优良，适合建筑行业使用。
