本レビューは、グラフェン系ナノシート（GNS）のコーティング技術（物理吸着、化学的自己組織化、電気泳動堆積、in situ成長）によるセメント系材料の高性能化を包括的に整理。ITZ（界面遷移帯）への局所配置により、強度、ひび割れ抵抗性、耐久性が向上し、カーボンニュートラルへの貢献が期待されるが、定量的なライフサイクル評価が不可欠。実用化にはコスト、長期安定性、実構造での検証が課題。
English
This review systematically summarizes graphene-based coating strategies (physical adsorption, chemical assembly, electrophoretic deposition, in situ growth) for cementitious composites. Targeted localization at ITZs enhances mechanical properties and durability, potentially contributing to carbon neutrality through reduced material consumption and extended service life. However, carbon benefits require quantitative life-cycle assessment, and challenges remain in large-scale implementation, long-term stability, and field validation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の建設業界では、インフラ長寿命化やCO2削減が喫緊の課題であり、本技術はコンクリートの高耐久化による材料使用量削減に寄与する可能性がある。ただし、現状は実験室レベルの知見が中心で、実用化にはコストや長期耐久性の検証が必要。
In the global GX context
For global GX, this review highlights graphene coatings as a promising route to lower the carbon footprint of concrete, a major CO2 source. However, the field lacks field-scale trials and comprehensive LCA, so practitioners should view carbon-neutrality claims cautiously. The work is primarily relevant to materials science and sustainable construction sectors.

📄 Abstract（原文）
Graphene-based nanosheets (GNS), including graphene, graphene oxide (GO), reduced graphene oxide (rGO), and graphene nanoplatelets (GNPs), have attracted increasing attention for developing high-performance and sustainable cementitious composites. Compared with conventional dispersion strategies, graphene-based coating strategies enable the targeted localization of GNS at critical interfacial transition zones (ITZs), thereby maximizing their reinforcing efficiency while mitigating agglomeration issues. This review systematically summarizes recent advances in GNS coating technologies for cementitious composites, including physical adsorption, chemical assembly, electrophoretic deposition, and in situ growth. The effects of GNS coatings on interfacial engineering, mechanical performance, durability enhancement, and smart functionalities are critically discussed. Existing studies indicate that GNS coatings can improve strength, crack resistance, impermeability, and resistance to chloride ingress, freeze–thaw cycles, and other degradation processes mainly through ITZ densification and microstructure refinement. However, these benefits are strongly dependent on the coating method, substrate type, and stability of the graphene–substrate interface in calcium-rich alkaline pore solutions. In particular, physically adsorbed GO coatings may suffer from desorption or Ca2+-induced aggregation, chemically assembled coatings require further validation beyond laboratory-scale systems, and electrophoretic deposition is mainly applicable to electrically conductive substrates. In addition, localized conductive networks created by GNS coatings facilitate multifunctional properties such as self-sensing, electromagnetic shielding, and electrothermal performance. From a carbon-neutrality perspective, the improvements in mechanical properties and durability provide opportunities to reduce material consumption, extend service life, and lower life-cycle carbon emissions. Nevertheless, their carbon-neutral contribution should be verified through quantitative life-cycle assessment rather than inferred directly from strength or durability enhancement alone. Finally, the remaining challenges associated with large-scale implementation, long-term stability, cost-effectiveness, and field-scale validation are discussed. Particular attention is given to the fact that most existing evidence is derived from laboratory-scale specimens rather than real structural elements exposed to service environments.
