Compressibility Characteristics of Soft Clays Treated by Graphene

It is extremely difficult to obtain a change in soil properties by incorporating graphene directly into the soft soil. Therefore, the stability of the soil or cementitious materials can be improved by treating them with graphene. Graphene is easily manufactured from pure graphite powder. Based on this aggregation, it may alter the final properties of graphene, because it completely depends on the raw chemicals and the method of building this material. The mechanical behavior of a new compound graphene was studied through consistency and compression. The soft clay used in this study is characterized with shear strength of 33.0 kPa. It is stabilized with 0.1 % of graphene with curing periods of 1 day and 7 days. It was observed that the void ratio decreased with addition of graphene under a given consolidation pressure. In addition, each of the swelling potential, the coefficient of volume compressibility and the coefficient of consolidation decrease with increasing the period of curing of graphene.
