At present time, there are vastly available of various nanomaterials, by using this material it plays an important role in various applications along with geotechnical soil stabilization/strengthen techniques. In the present investigation the addition of Graphene Oxide (GO) solution as nanomaterial into the low cemented fly ash (Class F – fly ash) to improving various properties of a local available silty soil. The various tests such as light compaction test, unconfined compression test, direct shear test, liquid limit, and plastic limit test were performed on the newly formed matrix to check their respective behavior to stimulated actual site condition on the given matrix in the laboratory. Also Scanning Electron Microscopy (SEM) analysis was performed to study the structure of the newly formed matrix. The addition of small proportion GO in original soil-fly ash matrix decrease the plasticity index and at the same time increase the maximum dry density, unconfined compression strength, and cohesion value help to use newly soil matrix effectively.
