adding graphene materials on the mechanical properties and durability of concrete

Abstract

Cement concrete, with its advantages of easy molding, good integrity, and significant economic benefits, is the most widely used building material in the world. However, the disadvantages of cement-based composites, including their inherent brittleness, low tensile strength, and susceptibility to corrosive environments, have always been major concerns. Within this framework, the application of nanomaterials and nanotechnology in cement-based materials has become the most attractive solution . Graphene, as a nanomaterial with a unique two-dimensional structure, offers new insights into improving concrete performance through its nano-filling effect and interfacial reinforcement. This study focuses on exploring the effects of different graphene oxide dosages on the workability, mechanical properties, and economic efficiency of concrete. This paper aims to provide a scientific understanding of the application of graphene materials in cement-based materials to promote their future practical application . The results show that the incorporation of graphene oxide effectively improves the compactness of concrete, reduces water absorption and dehydration rates, and enhances the compressive strength, splitting tensile strength, impermeability, resistance to chloride ion attack, and resistance to wet-dry cycles. The overall performance of concrete reaches its optimal state when the graphene oxide dosage is 0.050% . This study provides data support and theoretical basis for the application of graphene oxide in concrete.
