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.
