A critical review on the effect of graphene oxide in fiber reinforced cementitious systems.

AbstractThe most widely used building materials nowadays are aggregates and cementitious material composites. Recently, the Graphene Oxide (GO) nanomaterial has grabbed a lot of attention in the material science of building materials. These graphene oxide-based cementitious composites have been studied in terms of their effect on microstructure, hydration mechanisms, mechanical and durable properties, as well as the performance of GO-cement composites, which transform ordinary cement materials into intelligent, sturdy, and long-lasting composites. An overview of the contemporary state-of-the-art effect of cementitious composites containing GO with fiber addition is presented in this paper. The main purpose of this paper is to critically review GO's performance with fibers in cementitious composites. In this review, we examined the properties like Workability, mechanical properties, and durability of cement-based materials along with the microstructural characterization. The tailored property of cementitious composite made with graphene oxide and fibers controls not only the secondary hydration mechanism but also improves the material’s mechanical performance, robustness and other multifunctional properties. The interaction of GO nanomaterial with fiber results in a remarkable and unique performance, such as the improvement of gel pores, the decrease of bigger capillary pores, the bridging of microcracks and the resistance to their spread, and the overall performance improvement of cementitious composites. Thus, this article aims to provide a substantial critical review of the impact of GO and fibers in cementitious composites. [ABSTRACT FROM AUTHOR]
