将具有独特特性的纳米硅粉用作水泥土的一种新型添加剂。在试验的基础上，分析了纳米硅粉加固水泥土的强度特性。结果表明，纳米硅灰能显著提高水泥土在不同养护阶段的无侧限抗压强度。然后分析了纳米硅粉在水泥浆体硬化过程中的作用以及纳米硅粉和粘土的作用。分析了纳米硅粉在水泥土中的加固机理。为进一步研究纳米硅粉在土木工程领域中的应用，特别是在软基加固中的应用提供了启示。
The nanometer silica fume with particular characteristics was used as a new kind of additive for cemented soil. Based on the experiments, strength characteristics of nanometer silica fume reinforced cemented soil have been analyzed. The results suggest that nanometer silica fume can greatly improve the unconfined compression strength of cemented soil at various curing periods. Then, action of nanometer silica fume in the hardening process of cement paste and action of nanometer silica fume and clay are analyzed. The reinforcement mechanism of nanometer silica fume in cemented soil is analyzed. The paper will provide inspirations for further studies on application of nanometer silica fume in the field of civil engineering, especially in the reinforcement of soft soil foundation.
