| 中文摘要: |
| 为改善水泥固化软土效果，考虑碱激发作用，选择电石渣、生石膏、氯化钙、原状灰和硅酸钠作为辅助固化剂，采用无侧限抗压强度试验、X射线衍射、电镜扫描试验研究固化剂与硅酸盐水泥间的协同固化作用。通过正交试验确定出固化剂材料与水泥的最优配比。7 d和14 d龄期结果表明，在固化早期，电石渣的掺入量对强度影响效果最为突出，随着龄期推进，影响效果逐渐减弱。28 d龄期结果表明，氯化钙掺入量是影响固化土试样28 d龄期无侧限抗压强度的主要因素。 |
| 英文摘要: |
| In order to improve the effect of cement solidification on soft soil, alkali excitation is considered. Calcium carbide slag, sodium silicate, gypsum, undisturbed ash, and calcium chloride are selected as auxiliary solidification agents. Unconfined compressive strength tests, X-ray diffraction, and electron microscopy scanning tests are used to study the synergistic solidification effect between five auxiliary solidification agents and silicate saline mud. The optimal ratio of five auxiliary curing agents to cement was determined through orthogonal experiments. The results of the 7 d and 14 d curing periods indicate that in the early stage of solidification, the amount of calcium carbide slag added has the most prominent effect on strength, and the effect gradually weakens as the aging period advances. The 28 d age results indicate that the change level of calcium chloride addition ratio is the main factor affecting the unconfined compressive strength of solidified sludge samples at 28 d age. |
