Nowadays, soil stabilization has a vital importance due to the population growth, the
necessity of construction and natural unsuitability of soil for construction. The use of additives such as
lime and cement are one of the ways that can be applied for soil stabilization. Among new additives for
soil stabilization, it can be pointed out that Nano-Material is a more efficient and cost-effective method
with respect to traditional additives. One of this Nano-Material is Nano-Lime that can be used for soil
improvement. Therefore, in this research, the effect of Nano-Lime on soil resistance parameters was
investigated. For this purpose, behavior of soil specimens containing 0.5, 1 and 2% Nano-Lime that is
investigated under unconsolidated undrained triaxial after 7, 14 and 28 days curing. According to the
results, the values of maximum deviator stress are increased by adding Nano-Lime to the soil specimens,
and this trend raises by increasing percentage of Nano-Lime in the soil and curing days. That said, the
28-days maximum deviator stress of clean soil is increased by 21.3 to 38.3%, 27.0 to 59.3% and 29.6 to
70.8% with including 0.5%, 1% and 2% Nano-Lime for cell pressure 100, 200 and 300 kPa, respectively.
Moreover, it can be seen that both cohesion and stiffness of specimens containing Nano-Lime is raised
by increasing percentage of Nano-Lime in the soil and curing days.
