摘要: 粘土或泥页岩的比表面积与其膨胀压或水化趋势有函数关系,是表征泥页岩水化特性或
粘土膨胀量的指标。目前,测定粘土或泥页岩比表面积的方法较多,本文选择了两种方法进行对
比实验研究。结果表明, CST法是一种简便、省时且较为精确的方法。

Abstract: In argillaceous rocks, the composition and contents of clay mineral has determinat effect on its expansion and dis-persion. There is functonal relationship between specific surface of argillaceous rock and its expansive pressure on hydrat trend. It characterizes the indexes of hydrate properties or swell increment. Currently, there are many methods of swell surface testing. This paper selectes two available methods and are compared each other. It
shows that CST-nethods is easy, time-saving and accuracy.
