6Combining with several SEM pictures of different samples, cement-soilmicrostructure characteristics are described. Test results show that the cement-soil,whose stock-still time is longer, is a little worse of its strength than the one withoutstock-still time, because of its discontinuous microstructure and some micro-cracksbetween inter-particles.

6结合不同样品的SEM图片，描述了不同样品的微结构特征，试验结果表明，静置时间较长的水泥土由于微结构的不太致密、颗粒间存在较多的微裂缝，故其强度性能稍差。
