摘要:

通过模拟、对比试验和实例分析了用扫描电镜研究水泥浆体原始断面形貌的局限性，指出关键问题是水泥浆体内部的水化空间在很大程度上影响着水化物的形态，而水化空间则取决于水泥浆体的制备方法．

Abstract:

The limitation of scanning electron microscopy in research on the original frature surface of cement paste was discussed,in terms of the analoqous and contrasting experiments as well as the practical examples.The research results showed that the key problem is that the morphology of the hydrate phases is changed significantly with the sample grown within different free space,which deponds on the method of the preparation of samples.
