Experimental study of Nano-clay effect on geotechnical properties of Rasht soil

One of respects to improve soil and to change the ground on which construction is possible is to reform soil by using additive materials. Adding some pieces of additives to soil, as one of the effective technique to improve some behavioral parameters of soil, such as stress- strain, strength, permeability and self-repairing, specially in some geotechnical structure like soil dam, embankments, site of trash burning, projects of producing land and so on. have always been had in mind. These additive such as lime, calcium chloride, have been considered by researchers[5]. Nano-particles have been developed nanotechnology and much considered as a today science and technology. In this experimental study a different percent of Nano-clay Montmorillonite has been used in order to check out created 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 soil at the given percent of water. Test have been done in two ways, first by using Nano-clay for different percent and second by not using Nano-particles soil. The consequences of implemented test of the study show the improvement of soil properties by increasing low percent of Nano-clay; this improvement are kept fixed after a definite amount
