Building material for 3D printing and preparation method thereof
The invention discloses a building material for 3D printing and relates to the technical field of building materials. The building material comprises 20 to 40% of cement, 40 to 60% of sandstone, 1 to8% of quartz powder, 0.01 to 0.2% of an additive, 2 to 8% of silica fume, 0.01 to 1.5% of a composite stabilizing agent, 10 to 20% of water, 0.01 to 0.16% of a water reducing agent, 0.1 to 1.2% of fibers and 0.1 to 0.8% of a retarder. The preparation method comprises the following steps: mixing the cement, the sandstone, the quartz powder, the silica fume, the retarder and the fibers to obtain a mixed material A; mixing the water reducing agent and water to obtain a material B; and mixing the materials A and B to obtain the 3D printing material. According to the embodiment of the invention, the workability of the printable building material can be improved, the prepared building material is printed in various parameter ranges limited by the use method, and the smoothness of the printing process and the structural stability of the 3D printing material can be guaranteed.
本发明公开了一种用于3D打印的建筑材料，涉及建筑材料领域，包括：水泥20～40％，砂石40‑60％，石英粉1～8％，外加剂0.01～0.2％，硅灰2～8％，复合稳定剂0.01～1.5％，水10～20％，减水剂0.01～0.16％，纤维0.1～1.2％，缓凝剂0.1～0.8％。本发明还涉及一种制备方法，包括：混合水泥、砂石、石英粉、硅灰、缓凝剂和纤维得到混合物料A；混合减水剂和水得到物料B；混合A和B，得到3D打印材料。本发明实施例可提高可打印建筑材料的和易性，在使用方法限定的各项参数范围内打印所制备的建筑材料，可保证打印过程的顺利以及3D打印材料的结构稳定性。
