Version 3 adds 1% nano graphene and aluminum oxide each, enhancing conductivity for vehicle charging via a stainless-steel plate. Version 4 escalates this, using 1% nano graphene, 1.5% aluminum oxide, 1% zinc oxide, and 2% copper oxide, maximizing conductivity for wider applications like public parking. Each version showcases significant improvements in strength, conductivity, and functionality, addressing modern infrastructure needs.

Description

DescriptionTitle of Invention : Conductive Concrete CompositionTechnical Field

[0001] This product relates to the field of civil engineering, graphene-reinforced concrete.Background Art

[0002] Cementitious materials or cement composites are extensively used worldwide for building and construction, owing to their low-cost manufacture, easy shapeability and excellent compressive strength. Cementitious materials as the most ubiquitous construction materials are multiphase composites composed of amorphous phase, nanometer- to micrometer-size crystals, and bound water. However, the drawbacks of cement-based composites including its inherent brittleness, low tensile strength and proneness in the aggressive environments have always been the major concerns which may result in poor durability and high cost for its maintenance.

[0003] Numbers of methods have been proposed to improve the flexural strength, toughness and decrease microcracks in cement composites, such as adding usual reinforcing materials like steel fibers, natural fibers, glass fibers, carbon fibers and synthetic fibers. However, even though fibers can improve the flexural toughness of cement composites significantly by delaying the macro-cracks growth, whereas, they cannot inhibit the micro-cracks formation.

[0004] With the development of nanotechnology, many attempts have been made in introducing different nanomaterials into the cement composites such as nanosilica, nano-titanium dioxide, nano-clay, carbon-nanofiber (CNF) and carbon- nanotube (CNT) to achieve better mechanical properties, durability and multifunctionality of the cement composites.

[0005] Recent studies shows that among the many types of nanomaterial, graphene and its derivatives such as graphene oxide can be a good candidate to enhance the drawbacks of cement-based composites.Summary of Invention

[0006] This current work relates to investigate the influence of graphene oxide on the mechanical properties of concretes. For this purpose, different contents of graphene oxide were prepared for making different concrete admixture. As a uniform distribution of graphene oxide was needed inside the concrete matrix, each distinct weight of graphene oxide was first dispersed in water by ultrasonification and then the obtained homogeneous dispersion was added to the concrete admixture. After making different concrete, the produced graphene- reinfored concretes were compared with conventional concrete from mechanical point of view. The block diagram of the work is shown in figure 1 .Technical Problem

[0007] Concrete is a quasi-brittle material with a low capacity for deformation. This intrinsic brittleness is a weakness that requires further investigation for improvement.Solution to Problem

[0008] The weakness in mechanical properties of the concrete can be improved by the reinforcing effect of graphene oxide. Graphene oxide as a promising nano filler can fortify the engineering properties of concrete through the reduction of the pore structure of the concrete and the enhancement of the hydration degree of the cement.Advantageous Effects of Invention

[0009] The incorporation of graphene oxide in concrete can improve mechanical properties of the concrete.

[0010] The introduction of graphene oxide into the concrete matrix can enhance the hydration degree of cement.Brief Description of Drawings
