[0002] Concrete, commonly known as concrete: is the engineering composite material that is formed by cementitious material and aggregate. The commonly used concrete refers to the cement concrete that is prepared by mixing cement, sand and stone as aggregate, water (containing additive and admixture) in certain proportion and stirring. It is widely used in civil engineering. Concrete is one of the most important civil engineering materials in modern times. It is a kind of artificial stone that is prepared by mixing cementitious material, granular aggregate (also called aggregate), water and necessary additive and admixture in certain proportion, stirring uniformly, compacting and curing. The prestressed graphene conductive concrete structure is a new type of building material and structure form combined with concrete, graphene and prestressed technology in recent years. It has great potential in improving the electrical conductivity of concrete, enhancing the mechanical properties and improving the durability. The prestressed concrete is used to resist the tensile force in the use process by applying prestress in the concrete member, so as to improve the bearing capacity and durability. By applying prestressed reinforcement or steel cable before or during pouring, the development of cracks in concrete can be effectively controlled, and the bending and compression resistance of the member can be improved. Prestressed concrete is widely used in bridges, buildings, tunnels and other structures.
