(接上期)3.5真空饱和试验表5和图17说明了砂试样的真空饱和试验中收集的数据。未经处理的材料在浸泡阶段恶化,不能进行无侧限抗压强度或最终含水量试验。与7天试验的对照试样相比较,所有的处理后的砂试样都有强度损失,除了低、中、高浓度的二灰处理的试样分别增加了百分之46、23和30的强度。因为真空饱和试验只需要不到三个小时,这些强度的 (Continued) 3.5 Vacuum Saturation Tests Table 5 and Figure 17 illustrate the data collected during the vacuum saturation test for sand samples. Untreated materials deteriorate during the soaking phase and can not be tested for unconfined compressive strength or final moisture content. All treated sand samples had a loss in strength compared to the control samples for the 7 day test, except for low, medium and high concentrations of lime-ash treated samples that increased by 46, 23, and 30, respectively strength. Because the vacuum saturation test only takes less than three hours for these intensities
