This experimental study consists of the characterization of the epoxy grout where graphene nanoplatelets were added to commercial neat epoxy grout at an amount of 0.2%, 0.5%, 0.8% and 1.0% to evaluate their behaviour regarding neat epoxy grout. In order to study the characteristics of each type of grout epoxy, three tests were conducted which are compressive test, tensile test, and flexural test. By comparing graphene-based and neat epoxy grout, there is no significant increase in strength due to the weak interface in the graphene nanoplatelets/epoxy composite. Moreover, the tensile strength of tensile and compressive strength of modified grout epoxy is much lower than neat epoxy grout. Nevertheless, graphene modified grout showed more consistent results according to a smaller standard deviation of strength. In addition, modified grout epoxy shows an improvement in the ductility of the grout hence reducing the brittle behavior of the grout. With this result, the performance of graphene-based grout is able to minimize the sudden rupture and this is important due to repair design of damaged pipeline is of deterministic nature.References
