| 摘 要： | 以模拟非α低中放废液为固化处理对象,用水热法合成了非α低中放废液中和处理后沉淀的＂碱-矿渣-粉煤灰-偏高岭土＂水合陶瓷固化体。采用X射线衍射仪分析了固化体的水化产物,确定了水化产物的组成,并测试了固化体的抗压强度。研究结果表明：温度为150～180℃、废液沉淀与固化原材料的质量比值（即盐灰比）为0.10～0.30时,固化体水化产物的主要物相为方沸石,随着温度升高和反应时间延长,水化产物中方沸石的衍射峰不断增加。固化体抗压强度测试结果表明,该固化体具有较高的抗压强度,但盐灰比由0.10增加至0.30时,固化体抗压强度由26.33 MPa下降到8.46 MPa。 |
| 关 键 词： | 水合陶瓷固化体 非α低中放废液 水化产物 抗压强度 |
