【 摘 要 】

Totally contaminated soils is known as problematic soils. Also cohesive soil with low strength is not suitable for geotechnical structures. One of the soil improvement techniques is adding an additive to soil. Given the widespread use of nanoparticles in various fields, using these materials in order to improve geotechnical properties of these soils can be a new approach. In this experimental study, the effect of adding nanoclay and curing period on strength characteristic of kerosene contaminated soil and non contaminated cohesive soil was investigated. Hence unconfined compressive strength test carried out on these two types of soil samples with different proportions of nanoclay and different curing times. The unconfined compressive strength increases significantly by adding low percent of nanoclay. For example the strength of contaminated sample was increased 297% that contained 2% nanoclay and with 28 days curing time.
