摘要
利用ＳＥＭ和ＥＤＸ微区成分分析，探讨了掺有几种不同复合外加剂的集料－水泥石间界面过渡区内的Ｎａ＋分布。并发现界面过渡区内Ｎａ＋含量明显高于其它区域，而混合材的加入很好地改善碱性离子分布。
Taking use of SEM and EDX,the micro zone ingredients are analyzed The distribution of Na + in the transition zone of interface is discussed for the material mixal with composite agents And it is found that the content of Na + in the transition zone of interface is obviously higher than that in other zone With mixed materials,the distribution of alkaline ion can be improved greatly
