Similar material for extrusion type 3D printing of tunnel lining model
The invention relates to a similar material for extrusion type 3D printing of a tunnel lining model. The similar material comprises the following components in parts by weight: 35.03 to 35.38 parts of quartz sand; 8.76 to 11.1 parts of barite powder; 18.43 to 32.84 parts of silica fume; 21.89 to 36.85 parts of fly ash; 0.1 to 0.3 part of fiber; 0.12 to 0.99 part of quick hardening cement; 0.17 to 1.11 parts of Portland cement; and 0.1 to 0.8 part of a water reducing agent. Under the condition of low cement content, the ordinary cement and the quick-hardening cement are used as cementing substances, the standard sand, the barite powder, the silica fume and the fly ash are selected as aggregates, a lining similar material capable of being subjected to extrusion type 3D printing is obtained through a large number of experimental proportioning, and the lining similar material has good extrudability and constructability, adjustable mechanical parameters and certain toughness.
本发明为一种用于隧道衬砌模型挤出式3D打印的相似材料。所述相似材料包括以下重量份配比的组分：石英砂35.03‑35.38份；重晶石粉8.76‑11.1份；硅灰18.43‑32.84份；粉煤灰21.89‑36.85份；纤维0.1‑0.3份；快硬水泥0.12‑0.99份；硅酸盐水泥0.17‑1.11份；减水剂0.1‑0.8份。本发明在较低水泥含量下，以普通水泥和快硬水泥作为胶结物质，选用标准砂、重晶石粉、硅灰和粉煤灰为骨料，经过大量实验配比，得出能进行挤出式3D打印的衬砌相似材料，具有良好的挤出性、可建造性、力学参数可调整且具有一定的韧性。
