A review of Graphene Oxide (GO) performance on cementitious application

Conventional cementitious materials, while widely used in construction, suffer from inherent drawbacks, particularly low tensile strength, which predisposes them to crack. Fortunately, recent advancements in nanotechnology offer promising avenues for enhancing the properties of these materials. Within the realm of cementitious composites, graphene oxide (GO) has emerged as a nanomaterial of considerable interest due to its ability to significantly improve the strength of mortar and cement paste even at low inclusion levels. These remarkable characteristic positions GO as a potentially superior nano-filler for use in cement composites, paving the way for the development of more efficient, robust, and durable construction materials. This review delves into the existing body of research on GO-reinforced cement composites, specifically focusing on their mechanical performance, microstructural characteristics, workability, and durability. By critically analyzing these aspects, the review aims to identify key strengths and limitations associated with GO incorporation. Furthermore, the review highlights areas for further research that could facilitate the optimization and effective application of GO as a nano-reinforcing agent in cement composites. In conclusion, the review acknowledges the challenges associated with GO implementation while simultaneously emphasizing the exciting potential it holds for the future of construction materials.
