Reclaimed sand-doped ultrahigh-ductility cement-based ink material as well as preparation method and application thereof
The invention relates to a reclaimed sand-doped ultrahigh-ductility cement-based ink material as well as a preparation method and application thereof. The ink material comprises the following components in parts by weight: 80-120 parts of cement, 75-125 parts of an auxiliary cementing material, 5-25 parts of silica fume, 50-100 parts of reclaimed sand, 0.05-0.2 part of cellulose, 1-3 parts of fibers, 0.5-1 part of a water reducing agent and 40-80 parts of water. Compared with the prior art, the problems that a large amount of building solid waste cannot be effectively utilized and the like are solved, meanwhile, the tensile strain capacity of a 3D printing cement-based material is greatly improved, and the performance requirements for vibration reduction and shock resistance of a 3D printing concrete building are met.
本发明涉及一种掺再生砂超高延性水泥基油墨材料及制备方法和应用，该油墨材料包括以下重量份组分：水泥80‑120份、辅助胶凝材料75‑125份、硅灰5‑25份、再生砂50‑100份、纤维素0.05‑0.2份、纤维1‑3份、减水剂0.5‑1份和水40‑80份。与现有技术相比，本发明解决了大量建筑固废无法被有效利用等难题，同时大幅提升了3D打印水泥基材料的拉伸应变能力，利于3D打印混凝土建筑实现减振、抗震的性能要求。
