Modern concrete infrastructure requires structural components with higher mechanical strength and greater durability. A solution is the addition of nanomaterials to cement-based materials, which can enhance their mechanical properties. Some such nanomaterials include nano-silica (nano-SiO2), nano-alumina (nano-Al2O3), nano-ferric oxide (nano-Fe2O3), nano-titanium oxide (nano-TiO2), carbon nanotubes (CNTs), graphene and graphene oxide. These nanomaterials can be added to cement with other reinforcement materials such as steel fibers, glass, rice hull powder and fly ash. Optimal dosages of these materials can improve the compressive, tensile and flexural strength of cement-based materials, as well as their water absorption and workability. The use of these nanomaterials can enhance the performance and life cycle of concrete infrastructures. This review presents recent researches about the main effects on performance of cement-based composites caused by the incorporation of nanomaterials. The nanomaterials could decrease the cement porosity, generating a denser interfacial transition zone. In addition, nanomaterials reinforced cement can allow the construction of high-strength concrete structures with greater durability, which will decrease the maintenance requirements or early replacement. Also, the incorporation of nano-TiO2 and CNTs in cementitious matrices can provide concrete structures with self-cleaning and self-sensing abilities. These advantages could help in the photocatalytic decomposition of pollutants and structural health monitoring of the concrete structures. The nanomaterials have a great potential for applications in smart infrastructure based on high-strength concrete structures.

“…In order to understand the origin of the improvement of mechanical properties as well as the underlaying strengthening mechanism of GO, a tremendous effort is devoted to the investigation of hydration process, microstructure, and composition of GO‐based cementitious composites. Initially, the rate of hydration heat development has been explored [ 30,36,73–75 ] by means of isothermal calorimetry, which provides direct insight into the early age hydration kinetics of cementitious composites. The GO‐cement pastes feature with higher dissolution rate, [ 30 ] hydration rate, [ 30,36 ] as well as cumulative heat flow, [ 30,36,73 ] if compared to plain composites, being an indication of accelerated early age cement hydration and rapid nucleation of hydration crystals, albeit this effect may be also temporarily retarded, if PC is used to disperse GO nanosheets.…”

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.

“…It was found that the addition of graphene promotes the hydration reaction of both alite and belite, and thus leading to the formation of a large fraction of 3CaO•2SiO 2 •3H 2 O (C-S-H) phase. In fact, the 2D nanomaterials proved to be superior to the 1D and 3D nanomaterials, such as nanotubes and nanoparticles, in improving the mechanical properties of ceramic matrices [173]. A detailed review by Papageorgiou et al [24] summarizes the research on improving the mechanical properties of graphene nanocomposites.…”

In recent years, attempts to improve the mechanical properties of composites have increased remarkably owing to the inadequate utilization of matrices in demanding technological systems where efficiency, durability, and environmental compatibility are the key requirements. The search for novel materials that can potentially have enhanced mechanical properties continues. Recent studies have demonstrated that two-dimensional (2D) nanomaterials can act as excellent reinforcements because they possess high modulus of elasticity, high strength, and ultralow friction. By incorporating 2D nanomaterials in a composite, 2D nanomaterial-based composites (2DNBCs) have been developed. In view of this, a critical review of recent mechanical and tribological studies based on 2DNBCs has been undertaken. Matrices such as polymers, ceramics, and metals, as well as most of the representative 2D nanomaterial reinforcements such as graphene, boron nitride (BN), molybdenum disulfide (MoS2), and transition metal carbides and nitrides (MXenes) have been included in this review. Their preparation strategies, intrinsic mechanical properties, friction and lubrication performances, strengthening mechanisms, influencing factors, and potential applications have been comprehensively discussed. A brief summary and prospects are given in the final part, which would be useful in designing and fabricating advanced 2D nanocomposites in the future.
