Mortar material, preparation method and application thereof
The invention provides a mortar material as well as a preparation method and application thereof, and relates to the technical field of building materials. The mortar material is composed of the following components in percentage by mass: 15-25% of municipal waste incineration fly ash; 3%-15% of metakaolin; 3%-15% of fly ash; 1.3%-6.7% of silica fume; 28%-41.3% of water; 12.5%-16.5% of an alkali activator; 0.5%-2.5% of a thixotropic agent; 0.5%-20.8% of fine sand; and 1%-5% of fibers. The invention further provides application of the mortar material in the field of 3D building printing. The mortar material disclosed by the invention solves the problems that a printing material is relatively long in setting and hardening time, cannot meet the working performance of 3D building printing and is low in printing efficiency.
本发明提供了一种砂浆材料、制备方法及其应用，涉及建筑材料技术领域。按质量百分含量，所述砂浆材料由以下组分组成：城市垃圾焚烧飞灰15％‑25％；偏高岭土3％‑15％；粉煤灰3％‑15％；硅灰1.3％‑6.7％；水28％‑41.3％；碱激发剂12.5％‑16.5％；触变剂0.5％‑2.5％；细砂0.5％‑20.8％；纤维1％‑5％。本发明还提供了砂浆材料在3D建筑打印领域中的应用。本发明的砂浆材料解决了打印材料凝结硬化时间较长，无法满足3D建筑打印的工作性能以及打印效率低的问题。
