Expansive soils pose significant challenges in geotechnical engineering due to their high swelling and shrinkage potential, damaging structures and infrastructure. While various methods have been employed to address these issues, nano-conditioning using nanoparticles presents a promising avenue. Nanoparticles, due to their small size and large specific surface area, can interact profoundly with soil, impacting its physical, mechanical, and hydraulic properties. Due to the limited information available on the effects of nano-conditioning on expansive soils, our research adopts an extensive literature review approach. This approach involves gathering data and studies related to the use of nano-conditioning for general soil treatment, with a focus on factors pertinent to expansive soils' behavior. The results reveal the complex and context-dependent nature of nanoparticle-soil interactions. Nano-conditioning can enhance certain properties, like compressive strength and elastic modulus, while its impact on parameters such as plasticity index, cohesion, and friction angle varies depending on nanoparticle type and concentration.
