土壤中的有机物含量会抑制水泥稳定的有效性。该研究测试了各种外加剂与水泥的使用，以评估它们对所产生的颗粒尺寸和孔隙尺寸的影响，使用SEM图像和WD-5图像处理系统来确定结构单元和孔隙的形状参数。结果表明，不同的外加剂在稳定化过程中所起的作用不同。尽管具有水泥和促凝剂的样品以及具有硫酸铝的水泥是有效的，但是用水泥加结晶硫酸钙实现了最大的改进。
The organic content of a soil inhibits the effectiveness of cement stabilization. The study tested the use of various admixtures with cement to assess their effect on the size of the granules created and the size of the pores, using SEM imagery and a WD-5 image processing system to determine the shape parameters of structure units and pores. The results show that different admixtures play different roles in the stabilization process. Although the samples with cement and an accelerator and cement with aluminium sulfate were effective, the most improvement was achieved with cement plus crystal calcium sulfate.
