“…Additionally, nucleation in the pore space removes calcium and hydroxide ions from the solution, thereby creating a local concentration gradient away from the clinker particles, which further accelerates PC clinker dissolution [17,18]. In recent years, graphene has been deployed as nanoparticles to enhance the performance of cement-based materials [19][20][21][22][23] due to its outstanding properties to form graphene-reinforced cement composites for smart infrastructures. Graphene, a single-layer of sp2 bonded sheet of carbon atoms arranged into a 2D honeycomb lattice pattern (with an interlayer thickness of ~0.335 nm), has intrinsic high mechanical properties (i.e., the strength of ~100 GPa and the Young's modulus of 1 TPa [24]) therefore has potential to greatly improve the mechanical properties of cementitious materials.…”

“…Ordinary Portland Cement (OPC) is the most widely used cement binder in modern concrete applications. The manufacturing of OPC clinker results in utilizing massive quantities of natural resources and energy, which has an adverse impact on the environment [17][18][19][20][21]. It is estimated that 0.83 kg of CO 2 is produced during the production of 1 kg of cement clinker, which corresponds to the cement manufacturing industry bearing responsibility for nearly 6-8% of global CO 2 emissions [17,[22][23][24].…”

This review focuses on recent advances in concrete durability using graphene oxide (GO) as a nanomaterial additive, with a goal to fill the gap between concrete technology, chemical interactions, and concrete durability, whilst providing insights for the adaptation of GO as an additive in concrete construction. An overview of concrete durability applications, key durability failure mechanisms of concrete, transportation mechanisms, chemical reactions involved in compromising durability, and the chemical alterations within a concrete system are discussed to understand how they impact the overall durability of concrete. The existing literature on the durability and chemical resistance of GO-reinforced concrete and mortar was reviewed and summarized. The impacts of nano-additives on the durability of concrete and its mechanisms are thoroughly discussed, particularly focusing on GO as the primary nanomaterial and its impact on durability. Finally, research gaps, future recommendations, and challenges related to the durability of mass-scale GO applications are presented.

“…In addition, GO can also participate in the hydration process of cement to promote the hydration reaction of cement, thus enhancing the properties of cement‐based materials. [ 10–13 ] A few studies have investigated the effect of GO on the properties of cement‐based materials. Han et al [ 14 ] systematically elaborated on graphene‐engineered cementitious composites, indicating that GO is beneficial to improve the performance of concrete.…”

Herein, the properties of concrete containing graphene oxide (GO) and silica fume (SF) are systematically investigated. The results show that the excellent properties of GO and SF have a significant improvement effect on the performance of concrete. Among them, the compressive, splitting tensile, and flexural strength of B‐1 group (GO, 0.01 wt% and SF, 2.5 wt%) are increased by 11.04%, 12.23%, 20.11% compared with the reference group after 3 days of curing. Meanwhile, the water penetration height of B‐1 group is decreased by 59.67% compared with reference group. The mass loss and relative dynamic modulus loss are 5.32% and 8.89% after 75 freeze‐thaw cycles, which are much lower than the reference group. Moreover, the micromodification mechanism of GO and SF on the concrete is investigated by using X‐ray diffraction analysis, scanning electron microscopy, and mercury intrusion porosimetry. The results show that the incorporation of GO and SF promotes the early hydration reaction of cement, improves the internal structure of the matrix, and enhances the compactness of the matrix.
