中文摘要 | The autogenous volumetric stability of solidified saline soils was investigated to prevent damage to roads caused by volume changes of the road foundations. Specimens with the length of 290 mm were prepared for linear expansion/shrinkage measurements of soils containing various amounts of chlorine and sulfate radicals. The specimens were solidified by three types of soil stabilizers. The studies analyzed the effect of calcium ions, sodium ions, and water content on the expansion and shrinkage. The results show that chlorine causes little volume variation but sulfate radicals can cause significant expansion of the solidified soil. Slag-fly ash-cement stabilizer provides less calcium ions for chemical reactions than cement resulting in less expansion of the solidified saline soil specimens. When there are few calcium ions but many sodium ions, the chlorine and the sulfate radicals do not stimulate chemical reactions in the soil. The water content influences the spacing between soil particles and the expansion. |
