As, in recent years, liquefaction phenomena have occurred in sandy soils containing different amounts of clay content, it was concluded that, in addition to silty sands, clayey sands are also vulnerable to the liquefaction phenomenon. So, the urge for comprehensive study was aroused to cover the issue.In this paper, the effect of clay content and its plasticity properties on the behavioural characteristics of clayey sands under various density and confining pressure values has been investigated. To achieve the goal, about a hundred monotonic triaxial tests were performed on remolded specimens of sandy soil containing different clay content with different plasticity values. Based on the results, the latter factors affect peak strength, steady state strength and angle of internal friction, considerably. Furthermore, great results were obtained regarding the issue of whether clay content or plasticity property variations are more effective.
