3D printing foam concrete and preparation method thereof
The invention relates to 3D printing foam concrete and a preparation method thereof, and belongs to the technical field of foam concrete preparation. The 3D printing foam concrete is prepared by mixing slurry and foam according to a volume ratio of 0.40-1.50, the slurry is prepared from the following materials in parts by mass: 20 to 50 parts of ordinary Portland cement, 10 to 20 parts of fly ash, 25 to 45 parts of quartz sand, 10 to 15 parts of water, 2 to 5 parts of coagulation regulating component, 0.10 to 0.25 part of water reducing agent, 0.15 to 0.30 part of viscosity regulator, 0.10 to 0.30 part of shrinkage reducing agent, 0.3 to 0.60 part of expanding agent and 0.1 to 0.4 part of fiber. The lightweight foam concrete block with high strength, high crack resistance and heat insulation performance is prepared through a 3D printing means, the problem that printability and constructability are insufficient due to the fact that the flowability of common foam concrete is too large is solved, and the application scene of a foam concrete material is expanded.
本发明涉及一种3D打印泡沫混凝土及其制备方法，属于泡沫混凝土制备技术领域。该3D打印泡沫混凝土由浆料与泡沫按体积比0.40‑1.50混合而成；该浆料包括如下质量份数的材料：普通硅酸盐水泥20‑50份、粉煤灰10‑20份、石英砂25‑45份、水10‑15份，调凝组分2‑5份，减水剂0.10‑0.25份，粘度调节剂0.15‑0.30份，减缩剂0.10‑0.30份，膨胀剂0.3‑0.60份，纤维0.1‑0.4份。本发明通过3D打印手段制备了具有高强度高抗裂和具备隔热保温性能的轻质泡沫混凝土砌块，解决了普通泡沫混凝土流动度过大而导致可打印性和可建造性不足的问题，拓展了泡沫混凝土材料的应用场景。
