Underwater 3D printing cement-based material and preparation method thereof
The invention provides an underwater 3D printing cement-based material and a preparation method thereof, and relates to the technical field of preparation of cement-based materials. The underwater 3D printing cement-based material is prepared from the following components in parts by weight: 325 to 525 parts of a cementing material, 840 to 1050 parts of fine aggregate, 15 to 30 parts of an anti-dispersing agent, 25 to 50 parts of a thixotropic agent and 8 to 20 parts of a powdery polycarboxylic acid high-performance water reducing agent. And the underwater 3D printing cement-based material has excellent dispersion resistance, impermeability and interlayer bonding force.
本发明提供一种水下3D打印水泥基材料及其制备方法，涉及水泥基材料制备技术领域。一种水下3D打印水泥基材料，包括以重量份计的各组份：胶凝材料325‑525份、细骨料840‑1050份、抗分散剂15‑30份、触变剂25‑50份、粉状聚羧酸高性能减水剂8‑20份。水下3D打印水泥基材料的抗分散性、抗渗性及层间粘结力优异。
