| 中文摘要: |
| 采用具有耐高温性能优异的铝酸盐水泥制备一种铝酸盐水泥基3D打印复合材料，量化分析了3D打印铝酸盐水泥基复合材料常温力学性能以及经受150，350，550，750，950 ℃后的残余力学性能，通过采用热重-差示扫描量热法（TG-DSC）、扫描电子显微镜（SEM）和CT扫描技术研究材料微观结构的演变过程。结果表明：随着温度的升高，3D打印铝酸盐水泥基复合材料的抗折强度和抗压强度不断降低，失重率增加，水泥石结构孔隙率及裂缝不断增大。 |

| A type of aluminum salt water-based 3D printed composite material was prepared using aluminum salt cement with excellent high temperature resistance. The mechanical properties of the 3D printed aluminum salt water-based composite material at room temperature and the residual mechanical properties after being subjected to 150, 350, 550, 750 and 950 ℃ were quantitatively analyzed. The evolution process of the material's microstructure was studied using thermogravimetric differential scanning calorimetry (TG-DSC), scanning electron microscopy (SEM), and CT scanning techniques. The results showed that with the increase of temperature, the flexural strength and compressive strength of 3D printed alumina salt water-based composite materials continued to decrease, the weight loss rate increased, and the porosity and cracks of the cement stone structure continued to increase. |
