This document discusses using nano materials to stabilize soft soils. It begins by defining soil stabilization and describing conventional methods. It then defines nanotechnology and different nano materials that can be used like nano titanium oxide, fly ash, clay, magnesium oxide, copper oxide, and silica. It summarizes the effects each nano material has on soil properties like Atterberg limits, compaction characteristics, and unconfined compressive strength. The conclusion is that nano materials can improve soft soil properties by decreasing plasticity, increasing maximum dry density and compressive strength.
