Abstract: One of the ways to improve soil and to change the ground is to reform soil by using additive materials. Adding some additives to soil, as one of the effective techniques to improve some behavioral parameters of the soil, such as stress-strain, strength, permeability and self-repairing, specially in some geotechnical structure such as soil dams, embankments, site of trash Burning, projects of producing land and so on. Have always been in mind These additives such as lime, calcium chloride, have been considered by researchers [5]. Nano-particles have been developed for nanotechnology and much considered as a science and technology today. In this experimental study, a different percentage of Nano-clay Montmorillon has been used to check out the changes in soil characteristics with increasing percent of Nano-clay. For gaining optimal water percent and maximum specific weight compaction test have been done on soil and the direct shear test, unconfined compression test and Atterberg limits have been implemented on the soil at given percentage of water. Test has been done in two ways, first by using Nano-clay for different percent and second by not using Nano-particles soil. The effects of the implemented test of the study show the improvement of soil properties by increasing low percent of Nano-clay; This improvement is maintained after a definite amount
