Description
Summary:With its eventual release into the atmosphere, graphene oxide is considered an emerging environmental pollutant. As a result, its possible environmental and biosafety threats are attracting more publicity. Due to the underlying soil properties, adding graphene oxide directly into the soft soil is difficult to change soil properties. This study aims to see if graphene oxide can be used as a stabilizing medium to increase the strength and compressibility of soft clay. The soft clay used in this analysis has a shear strength of 33.0 kPa. It has a curing time of 1 day and 7 days and is stabilized with 0.1 percent graphene oxide. It was discovered that as the curing time of graphene oxide increases, the soil compressibility (Cc and Cs) decreases. The coefficient of consolidation (Cv) decreases as the curing time of graphene oxide is increases. The graphene oxide content and curing time increased the soil’s shear strength. After 7 days of curing, the unconfined compressive strength can increase by 350 percent.
