Abstract

The use of stabilizing technologies has significantly expanded in recent years specially when sites are frequently construction in poor land locations. This study suggests using nano-silica to improve clayey soil's functionality. A range of nano-silica concentrations (0, 0.1, 0.2, 0.4, and 0.8) were used. Laboratory testing was used to identify Atterber's limitations, the optimum moisture content (OMC), the maximum dry density (MDD), and microstructural examination. According to the study, treating soil with 0.4-0.6% nano-silica yields the best results. According to the result, the liquid limit (LL) and plastic limit (PL) are reached maximum at 0.6% nano-silica, while the plasticity index is at its lowest point. The results showed that incorporating nano-silica into clay samples will lower the maximum.

纳米二氧化硅材料增强粘性土的稠度和压实特性

近年来，稳定技术的使用已大大扩大，特别是当场址经常建在贫瘠的土地上时。本研究建议使用纳米二氧化硅来改善粘性土的功能。纳米二氧化硅浓度范围(0、0.1、0.2、0.4和0.8)被使用。通过实验室测试确定了Atterber极限、最佳含水率(OMC)、最大干密度(MDD)和显微组织检查。研究表明，以0.4-0.6%纳米二氧化硅处理土壤效果最好。结果表明:0.6%纳米二氧化硅的液限(LL)和塑性极限(PL)达到最大值，塑性指数最低;结果表明，在粘土样品中掺入纳米二氧化硅可以降低其最大值。
