3D printing concrete capable of absorbing waste glass powder and preparation method thereof
The invention discloses 3D printing concrete capable of absorbing waste glass powder and a preparation method thereof, and belongs to the technical field of concrete materials and preparation thereof. The 3D printing concrete capable of consuming the waste glass powder, provided by the invention, is prepared from the following raw materials in parts by weight: 796.45 to 937 parts of ordinary Portland cement, 33.9 to 140.55 parts of the waste glass powder, 80 parts of sulphoaluminate cement, 79.1 to 113 parts of silica fume, 395.5 parts of water, 1000 parts of river sand, 0.45 part of cellulose ether, 2.26 parts of a water reducing agent, 2.37 parts of a de-foaming agent and 2.7 parts of rubber powder. By reasonably using the waste glass powder, the environment-friendly 3D printing concrete material which is suitable for an extrusion type 3D printing concrete technology and has good printability is prepared, meanwhile, the concrete strength is improved, the pore structure is refined, the carbon emission is reduced, and recycling of waste glass resources is promoted.
本发明公开了一种可消纳废弃玻璃粉的3D打印混凝土及其制备方法，属于混凝土材料及其制备技术领域。本发明提供的可消纳废弃玻璃粉的3D打印混凝土包括如下重量份原料：普通硅酸盐水泥796.45‑937份、废玻璃粉33.9‑140.55份、硫铝酸盐水泥80份、硅灰79.1‑113份、水395.5份、河砂1000份、纤维素醚0.45份、减水剂2.26份、消泡剂2.37份、胶粉2.7份。本发明通过合理地使用废弃玻璃粉，制备出适用于挤出式3D打印混凝土技术的具有良好可打印性的环保3D打印混凝土材料，同时提高混凝土强度，细化孔隙结构，并降低碳排放量，促进了废旧玻璃资源的循环再利用。
