Abstract

The release of oil pollutants in the soil causes changes in the structure, texture and the relationship between the soil particles. This has destructive effects on the physical and mechanical properties of soils. In recent years, improvement of degraded engineering properties of these soils for their use in construction projects has been a challenge for researchers and engineers. In this paper, the effect of adding two types of clay nanoparticles on the improvement of mechanical properties of Clayey Sand contaminated with gas-oil has been investigated. For this purpose, after determining the basic properties of natural soil, soil with 6% and 8% gas-oil, contaminated soil stabilized with nano-clay in values of (0.5, 1, 2 and 3%) and organo-clay in values of (0.3, 0.5, 0.7 and 1%), standard compaction and unconfined compressive strength tests during the two curing periods (7 and 28 days) were performed on them. Scanning electron microscopy (SEM) was also used to evaluate the microstructure of natural soil samples. Also, the microstructure of natural soil, contaminated soil and contaminated soil stabilized with nanoparticles was studied with the help of SEM. The results of the tests showed that maximum dry density, optimum water content, and unconfined compressive strength have decreased in the soil with gas-oil. The stabilization of contaminated soil using clay nanoparticles showed that adding 2% of nano-clay to contaminated soils of 6 and 8% of gas-oil resulted in the highest increase in compressive strength of 58% and 56%, respectively. In addition, adding 0.7% organo-clay to soil containing 8% of gas-oil leads to an increase of 37.56% in compressive strength. It was also observed that the addition of nano-clay and organo-clay to the contaminated soil resulted in an increase in optimum water content and a decrease in the maximum dry density. In general, it can be concluded that the contaminated soil with gas-oil has the potential to improve strength properties by adding clay nanoparticles.
