Abstract
Soil being particulate system encompasses a wide variety of particles, which has made it one of the most complicated natural materials to be modeled. Among soils, soft soil deposits pose challenging problems to geotechnical engineers for the assessment of reliable behavior of these soils to be used either as a foundation medium or construction material. In this study, nano-material additives have been chosen to investigate their influence on strength behavior of clayey soil. Two soil samples are treated with nano-material additives of nano-copper (CuO) and nano-gypsum (CaSO4·2H2O) at varying percentages of 0.5%, 1.0%, 1.5% and 2.0%, respectively. The test results revealed that the soil unconfined compressive strength increased significantly with increasing nano-material additives. However, the optimum value of nano-material additives content was observed around 1.5%. Therefore, the main goal of this study was to stabilize soft soil deposits for its bulk utilization in various geotechnical applications for sustainable environment.
