Enhancement of Clay Compressibility and Strength Using Nano Magnesium Oxide

In order to satisfy the requirements of environmentally friendly construction projects and minimize greenhouse gas emissions, it was necessary focus on utilizing nanomaterials instead conventional materials enhance clay soils; nano Magnesium Oxide suggested for this study. The compression unconfined compressive strength tests were achieved assess compressibility behavior silty treated using magnesium oxide. Additionally, an investigation into alteration microstructure conducted field emission scanning electron microscopy (FE-SEM) tests. utilized in research is characterized by a index 0.23 undrained shear 53 kPa. soil adding different percentages nano-MgO (0.4%, 0.5%, 0.6%, 0.8%), curing period seven days. samples prepared based optimal water content maximal dry density natural soil. results indicate that utilization leads reduction both values (Cc) recompression (Cr), addition decrease value coefficient (av). Also, test finding demonstrates noticeable increase as percentage increases, accompanied failure strain. Adding 0.6% (the optimum percentage) oxide enhances about 114% decreases 36% compared with
