Application of Graphene in Fiber-Reinforced Cementitious Composites: A Review

Abstract

Graphene with fascinating properties has been deemed as an excellent reinforcement for cementitious composites, enabling construction materials to be smarter, stronger, and more durable. However, some challenges such as dispersion issues and high costs, hinder the direct incorporation of graphene-based reinforcement fillers into cementitious composites for industrial production. The combination of graphene with conventional fibers to reinforce cement hence appears as a more promising pathway especially towards the commercialization of graphene for cementitious materials. In this review paper, a critical and synthetical overview on recent research findings of the implementation of graphene in fiber-reinforced cementitious composites was conducted. The preparation and characterization methods of hybrid graphene-fiber fillers are first introduced. Mechanical reinforcing mechanisms are subsequently summarized, highlighting the main contribution of nucleation effect, filling effect, interfacial bonding effect, and toughening effect. The review further presents in detail the enhancements of multifunctional properties of graphene-fiber reinforced cementitious composites, involving the interfacial properties, mechanical properties, durability, electrical conductivity, and electromagnetic interference shielding. The main challenges and future prospects are finally discussed to provide constructive ideas and guidance to assist with relevant studies in future.

Study of the Structure and Properties of Electrical Sand Concrete under Prolonged Exposure to Sulfate Environment

“…A review of existing studies shows that the first attempts to regulate the electrical properties of cement matrices were first described in [ 10 , 11 ]. There are three types of electrically conductive structures formed in the mineral matrix: cluster [ 12 , 13 ], linear [ 14 ], and complex [ 15 ]. To obtain each of the types, different types of additives are used: finely dispersed powders, predominantly round in shape, and particles with relative elongation [ 13 , 14 , 15 ].…”

To obtain each of the types, different types of additives are used: finely dispersed powders, predominantly round in shape, and particles with relative elongation [ 13 , 14 , 15 ]. Due to the peculiarities of the electrical conductivity [ 7 ] of the mineral matrix based on Portland cement, additives such as carbon-containing materials, fiber based on various types of metals, dispersed powders in the form of metal oxides or a mixture of doped oxides can be used to reduce the electrical resistivity [ 16 , 17 ].…”

Recent Progress in Flexible Graphene-Based Composite Fiber Electrodes for Supercapacitors

“…Extensive studies have found that graphene outperforms other carbon materials in terms of electrical and thermal conductivity as well as weavability when used for fiber electrodes [22][23][24][25][26][27]. As an emerging material in the field of energy storage, graphene has shown the world its fascinating properties, such as high impermeability [28][29][30], high electron mobility [31], high thermal conductivity [32,33], superlubricity [34][35][36], extraordinary elasticity and stiffness [37,38]. Particularly, the high electrical conductivity of graphene sheets could avoid the inclusion of conductive additives and enhance the energy density of graphene-based electrodes.…”
