Recycled cement-based material based on 3D printing and preparation method thereof
The invention provides a recycled cement-based material based on 3D printing and a preparation method thereof. The recycled cement-based material is prepared from, by mass, cement, ceramic powder, coal ash, graphite tailings, river sand, water, a water reducing agent, a thickening agent and basalt fibers, wherein the ratio of the cement to the ceramic powder to the coal ash to the graphite tailings to the river sand to the water to the water reducing agent to the thickening agent to the basalt fibers is 100: 0-29: 0-14: 0-57: 0-170: 0-56: 0.01-0.8: 0.01-1.7: 0.01-0.5. Resources can be effectively utilized, resource waste and environmental pollution are reduced, the prepared recycled cement-based material has proper fluidity and excellent extrudability, forming effect, constructability and compressive strength, high-quality engineering products can be obtained, the recycled cement-based material is applied to 3D printing, overall engineering time is short, labor consumption is low, and cost can be reduced.
本发明提供了一种基于3D打印的再生水泥基材料及其制备方法，所述再生水泥基材料包括以下的成分：水泥、陶瓷粉、粉煤灰、石墨尾矿、河砂、水、减水剂、增稠剂、玄武岩纤维，且按照质量比，所述水泥、所述陶瓷粉、所述粉煤灰、所述石墨尾矿、所述河砂、所述水、所述减水剂、所述增稠剂以及所述玄武岩纤维的比例为：100：0‑29：0‑14：0‑57：0‑170：0‑56：0.01‑0.8：0.01‑1.7：0.01‑0.5。本发明能有效利用资源，减少资源浪费以及环境污染，制备的再生水泥基材料具有适宜的流动性以及优异的可挤出性、成型效果、可建造性以及抗压强度，能获得高质量的工程产品，应用在3D打印中，总体的工程时间短，人力耗费低，有助于降低成本。
