“…The compressive strength of GP-modified cementitious materials in the literature is normalized and presented in Table 2. The compressive strength of GPmodified cementitious materials is not significantly improved, and the most effective improvement is 122.86% relative strength rate obtained at 0.1% GP in the examination by Sharma and Arora [58]. In the study by Bai et al [59], adding 0.1-2% GP to the cement paste results in the reduced compressive strength.…”

“…The nanosheet-modified cement material provides a new method to solve this problem. Sharma and Arora [58] studied the sulfate attack resistance of GP-cement mortar, and 0.05% GP modified mortar can achieve excellent resistance to sulfate attack. The relationship between the sulfate exposure time and the percentage decrease of the compressive strength is shown in Figure 5.…”

AbstractEmerging nanomaterials provide an invaluable opportunity for the development of cementitious materials. Many scholars have explored the influence of graphene (GP) and graphene oxide (GO) on the performance of the cementitious materials. This article reviews the previous research on the effect of GP and GO on the properties of cementitious materials. Detailed review of the mechanical properties and durability of cementitious materials containing GP or GO nanofilms is presented, and the mechanism is discussed. The mechanical properties of GO-cementitious materials are significantly enhanced. The optimal improvement of GO-modified compressive, flexural, and tensile strengths is 77.3%, 78.3%, and 78.6%, respectively. The durability of GO- and GP-modified cementitious material is compared with the control group. The incorporation of GP or GO significantly improves the sulfate attack resistance, and the transport properties can be decreased, while the frost resistance of GO- and GP-modified cementitious materials needs further research. This literature review shows that the microstructure of GO- and GP-modified cementitious material is improved in three aspects: accelerating the cement hydration, refining the pore structure, and hindering the crack propagation.

“…One of the ways to deal with the problem of excessive consumption of raw materials is reducing the dependence on traditional cement and creating a demand for alternative cement products ( Tamanna et al., 2020 ). Some researchers aim to replace materials that cause an environmental impact due to cement production, either by technological improvements or by the simple addition of residual material, such as bottom ash ( Sharma and Arora, 2018 ).…”

With an increase in climate and environmental issues awareness, the use of waste of various types has gained increased visibility, acknowledging that wastes are any and all kinds of unused materials from the production process or after using the final product for its intended purpose. The use of wastes to produce alternative cement materials is an alternative to reduce the use of natural resources. Forestry residues, ash, plastic residues, LDPE/Al composites, and geopolymer materials are some of the possible residues used for the partial replacement of cement materials. The objective of this research is to establish how these materials relate to each other, based on a topic review and how they can contribute towards sustainability. The study was performed on several scientific article search engines, in which the keywords ‘Carton Packages’, ‘Wood Waste’ and ‘Geopolymers’ were inserted, and then a refinement was carried out using the term ‘Cement Materials’. Such analysis allowed the generation of information related to publication numbers, countries, research areas, as well as publication types. Co-authorship networks of organization, co-citation of references, co-occurrence of keywords, among others, were also plotted. Through this bibliometric analysis, it was possible to reveal the structure of the research, analyse the developments and predict the future directions for the research regarding the use of residues in the production of sustainable Portland cement composites.

“…The mixing of fly ash PPC and GO improved the workability of the composites. Sharma and Arora [62] used fly ash PPC as the matrix and added graphene as reinforcements. At a concentration of 0.05 vol% graphene, the flexural and compressive strength were increased by 13% and 8%, respectively.…”

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.
