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.
Abstract
A type of aluminum salt water-based 3D printed composite material was prepared using aluminum salt cement with excel-lent 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 ana-lyzed.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 tempera-ture,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.
