Abstract

Abstract: Since the mid-2000s, the transformation for the advanced 21st-century construction material has been on a headway utilizing the cutting-edge nanomaterials includes nano-silica, Carbon Nanotubes (CNTs), and Graphene Oxide (GO). GO is a recently invented only 2D carbon-based nanomaterial as it provides an additional dimension for the reactivity with cement composites. GO is an irresistible nanomaterial as it reforms the cement composite ranging from the atomic scale to macroscale and strengthens the mechanical properties (viz., compressive strength, tensile strength, flexural strength, and Young's modulus), durability and other multifunctional behavior. The availability of larger surface area and various oxygen-based functional groups form a linkage and contributes to the impressive behavior of the cementitious matrix. This research article presents a comprehensive review of the performance and behavior of cementitious composites tailored with GO nanomaterial. Highlights: GO nanomaterial in cement composite is a completely novel and emerging area in the advanced construction technology. GO strengthen the cement composites from the atomic scale to the macroscopic scale. GO promotes the secondary hydration mechanism of Fly Ash. GO reveals its massive potential for the enhancement in durability and mechanical behavior of cementitious composite.
