An intense review on the performance of Graphene Oxide and reduced Graphene Oxide in an admixed cement system

Abstract

This paper reviews the current state of the art performance of Graphene Oxide (GO) and Reduced Graphene Oxide (rGO) addition in cement composites. GO has regarded as an excellent Nano-filler in cement composites by the extraordinary properties. In this study, performance aspects such as workability, durability, mechanical and microstructural characteristics of GO reinforced cement composites were reviewed. Interaction of GO with several mineral admixtures such as fly ash, silica fume and geopolymer composites in an admixed cement system was comprehensively discussed. This is the first paper to review GO performance with various mineral admixtures and to discuss and distinguish performance rGO in cement composites. Effects of reducing oxygen functional groups while producing rGO and the performance of rGO have been elaborated. rGO reinforcement in cement composites possesses a new research direction. Enhancements and drawbacks by reinforcing GO and rGO were reviewed till date. Recent extensive research on the performance of GO-cement composites has reviewed to transform conventional cement materials into smart, strong, and durable composites. This review provides an overview of performance, recent developments and fabrication of GO-cement composites in enhancing mechanical performance, durability, of cement composites. Concluding remarks stated indicating challenges and future perspectives on how to effectively use GO as a Nano-reinforcing material in cement composites.
