Abstract
Three green three-dimension printing concrete (3DPC) mixtures were made with biochar (BC), waste wind turbine blade powder (WTBP), and a pre-packaged 3DPC material (Sika-752). The mixtures were used to print small and larger beams with various fill patterns/rates. The results indicate that use of 3%BC (wetted with mixing water) and10% WTBP improved fluidity, especially slump, of the 3DPC mixture. 3%BC slightly reduced strength and ductility of the 3DPC. 10% WTBP decreased strength but increased ductility of the printed specimens. Optimized infill can improve load capacity. The use ofBC and WTBP in 3DPC has promising potential in construction engineering applications.
