元素分布
1.
The elements distribution characteristics in the interfacial transition zone between lightweight aggregate and cement paste were studied by backscattered electron imaging and EDXA.
研究了高强页岩陶粒与水泥石及其界面区的元素分布特征,探测出界面区宽度约为20~30μm,研究表明界面区Ca2+向轻集料方向迁移、轻集料内水分向界面区扩散,结果使得界面区的硅钙比较基体小,结构较基体密实,显微硬度较基体大;分析了粉煤灰、矿渣对两相界面组成、结构与性能的影响规律,结果表明随着粉煤灰、矿渣的掺入,界面区硅钙比增大,界面区水泥石的孔隙率和平均孔径显著降低,显微硬度提高,界面得到增强。
2.
Based on the observation of SEM and EDXA technologies,the investigation on the micro-structural properties and the elements distributional characteristics of Interfacial Transition Zone(ITZ)of recycled concrete is conducted.
界面过渡区内外的元素分布规律存在着较大的差异,Ca、Si等元素在界面过渡区内出现了一定程度的聚集,在界面过渡区外的分布则较为连续。
补充资料:稀土元素球粒陨石标准化分布型式
分子式:
CAS号:

性质:样品的稀土各元素含量除以球粒陨石相应元素的丰度值所得比值,称为稀土元素球粒陨石标准化值。将此数据投点于横坐标为按原子序数排列的各稀土元素、纵坐标为球粒陨石标准化对数值的图上,用直线依次连接各相邻元素的投点,得到的形状不同的曲线,称为稀土元素分布型式。
