“…Moreover, rGO offers also a great control over the formation of thermal cracks of cement composites by improving the heat propagation and thus minimizing the heat differences between the edges and the surface of cement mortar specimens, as reported by Jing et al. [ 84 ] Clearly, Figure 6c shows that reference cement paste exhibited many high thermal flux regions, the indication of the non‐uniform heat distribution, while the effective propagation of heat in time was achieved in rGO‐cement samples where the distribution of heat flux appeared as relatively homogenous.…”

The search for technological solutions to the ever‐increasing demand for ultra‐high‐quality concrete with the simultaneous construction boom represents one of the greatest challenges concrete researchers are facing nowadays. In view of their unique properties, graphene and related materials, when utilized to form graphene‐based cementitious composites, appear to be powerful components to give a boost to today's concrete technology. In this review, the most enlightening recent advancements in the development of fabrication protocols for obtaining the homogenous dispersion of graphene and derivatives thereof within the cement matrix are showcased. The hydration process and basic properties of graphene‐based cementitious materials are also discussed. The integration of graphene‐family materials to concrete technology allows new functions to be imparted to cement composites toward the construction of smart and multifunctional buildings. Therefore, a specific focus is given to the electrical and piezoresistive behavior of graphene‐cement composites, and ultimately their great potential for structural health monitoring applications. The approaches proposed in this review can be also extended to other 2D materials offering the broadest arsenal of physical properties, which can therefore be integrated on‐demand in future smart structures and constructions.

“…Similarly, the incorporation of 0.1% reduced GO (rGO) improved the compressive strength along with other properties (water absorption, ultrasonic pulse velocity, carbonation and fire resistance) [ 154 ]. Thermal conductivity and thermal diffusivity coefficient were also found to improve when using 1.2 wt % rGO [ 155 ].…”

This review is an update about the addition of nanomaterials in cementitious composites in order to improve their performance. The most common used nanomaterials for cementitious materials are carbon nanotubes, nanocellulose, nanographene, graphene oxide, nanosilica and nanoTiO2. All these nanomaterials can improve the physical, mechanical, thermal and electrical properties of cementitious composites, for example increase their compressive and tensile strength, accelerate hydration, decrease porosity and enhance fire resistance. Cement based materials have a very complex nanostructure consisting of hydration products, crystals, unhydrated cement particles and nanoporosity where traditional reinforcement, which is at the macro and micro scale, is not effective. Nanomaterials can reinforce the nanoscale, which wasn’t possible heretofore, enhancing the performance of the cementitious matrix.

“…Pisello et al [20] compared four nano-inclusions and found that graphene nanoplatelet (GNP) was the most effective nano-inclusion to improve the thermal conductivity of CCMs, enhancing the value from 0.78 W•m −1 •K −1 to 1.14 W•m −1 •K −1 . There are many other works on the mechanical and thermal properties of graphene reinforced cement composite materials (GRCCMs) [21][22][23][24][25][26][27][28][29][30][31][32].…”

Due to their excellent combination of mechanical and physical properties, graphene and its derivatives as reinforcements have been drawing tremendous attention to the development of high-performance and multifunctional cement-based composites. This paper is mainly focused on reviewing existing studies on the three material properties (electrical, piezoresistive and electromagnetic) correlated to the multifunction of graphene reinforced cement composite materials (GRCCMs). Graphene fillers have demonstrated better reinforcing effects on the three material properties involved when compared to the other fillers, such as carbon fiber (CF), carbon nanotube (CNT) and glass fiber (GF). This can be attributed to the large specific surface area of graphene fillers, leading to improved hydration process, microstructures and interactions between the fillers and the cement matrix in the composites. Therefore, studies on using some widely adopted methods/techniques to characterize and investigate the hydration and microstructures of GRCCMs are reviewed and discussed. Since the types of graphene fillers and cement matrices and the preparation methods affect the filler dispersion and material properties, studies on these aspects are also briefly summarized and discussed. Based on the review, some challenges and research gaps for future research are identified. This review is envisaged to provide a comprehensive literature review and more insightful perspectives for research on developing multifunctional GRCCMs.
