3D printing concrete material containing coarse aggregate and manufacturing method of 3D printing concrete material
The invention discloses a 3D printing concrete material containing coarse aggregate and a preparation method thereof, and the concrete material comprises the following components in percentage by weight: 35-48% of a cementing material, 5-7% of compound fiber, 6-12% of a mineral admixture, 1-2% of nano clay, 15-28% of compound fine aggregate, 12-24% of coarse aggregate, 0.5-1% of a water reducing agent, 1-2% of cellulose ether and 10-12% of water. The compound fibers are mainly formed by compounding basalt fibers and steel fibers which are graded in length, after the length gradient is constructed, the fibers with different lengths can be lapped in length, a fiber net formed during printing can be more complete through reasonable and scientific fiber length grading, a blank area is prevented from being covered, and the printing quality is improved. The integrity and constructability of the concrete material are guaranteed, and the compression resistance and bending resistance of a building formed through 3D printing are higher.
本发明公开一种含粗骨料的3D打印混凝土材料及其制备方法，按照重量百分比计，该混凝土材料包含35‑48%胶凝材料、5~7%复配纤维、6~12%矿物掺和料、1~2%纳米粘土、15~28%复配细骨料、12~24%粗骨料、0.5~1%减水剂、1~2%纤维素醚、10~12%水。复配纤维主要由长度形成级配的玄武岩纤维和钢纤维复合构成，构建长度梯度后，可使不同长度的纤维长短搭接，合理科学的纤维长度级配可使得在打印时形成的纤维网更加完整，避免出现覆盖空白区域，保证混凝土材料的整体性和可建造性，3D打印成型的建筑的抗压和抗折弯能力更强。
