“…[ 34 ] have reported that also the addition of fly ash prevents the flocculation of GO, thus increasing the fluidity of GO‐cement mix. Moreover, the chemical functionalization of GO with polyether amines (Figure 2b), [ 49 ] coating of cement particles with GO in isopropanol suspension, [ 50 ] and using the edge‐oxidized GO produced by ball‐milling treatment [ 51 ] (Figure 2c) represent additional valuable, yet complex methods developed recently for the fabrication of GO‐cement composites.…”

“…Intuitively, since the chemical reduction of GO with the use of hydrazine hydrate or sodium borohydride may partially restore its conductivity and strength, [ 16 ] rGO seems to be a promising alternative for high‐performance cementitious composites. However, the present research involving rGO‐cement composites remains highly limited, while the studies already published [ 36,50,81 ] have shown that, due to the reduced number of oxygen functional groups, the beneficial effect of rGO on the performance of cement composites is strongly inhibited. In fact, few extensive comparisons [ 36,50,81 ] have revealed that rGO fosters cement hydration and affects positively the microstructure and mechanical properties of cement composites, yet, the effect of GO was far more favorable.…”

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.

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.

The primary purpose of this investigation was to find out whether it would be feasible to successfully replace Ordinary Portland Cement (OPC) with 5, 10, or 15 mass % of activated alum sludge waste (AAS) as a pozzolanic material. This was the overarching question that guided the research that was conducted. A study into the use of low-cost nanocomposites to increase the physical, mechanical, and stability against the fire of OPC–AAS-hardened composites was carried out. The goal of this inquiry was to explore the utilization of low-cost nanocomposite. Producing CuFe2O4 spinel nanoparticles with an average particle size of less than 50 nm was doable. The introduction of CuFe2O4 spinel into a variety of OPC–AAS-hardened composites improve both the physicomechanical characteristics of the composites at nearly typical curing ages as well as the resistance of the composites to the effects of fire. Techniques such as TGA/DTG and XRD were utilized to provide evidence that synthesized CuFe2O4 spinel had favorable properties. These approaches revealed the presence of a range of hydration yields, such as CSHs, CASHs, CFSHs, and CuSHs, which improve the overall physicomechanical parameters as well as the thermal stability of a wide variety of OPC–AAS-hardened composites. The composite material that is composed of (90 % OPC, 10 % AAS waste, and 2 % CuFe2O4 offer several advantages, both financially and ecologically.
