In this study, a low-cost and industrially scalable graphene nanofluid additive (GNA) was incorporated into carbon fibre-reinforced cement mortar (CFRCM) to enhance its functionalities. The results indicated that the synergistic effect of the carbon fibres and the GNA significantly improved many properties of the cement mortar. For the CFRCM modified with GNA (G-CFRCM), the maximum increases in the flexural and compressive strengths, 101% and 126%, respectively, which were much greater than those of the control, 25% and 45%, respectively, and the maximum increases in the thermal and electrical conductivities of the G-CFRCM, 36% and 68%, respectively, were much greater than those of the control, 27% and 19%, respectively. In addition, a surprising increase in the service life of the corresponding cathodic protection system with the G-CFRCM, more than 200% compared to that of the control showed, that this novel composite material is ideally suited for applications in high-efficiency cathodic protection systems.

在这项研究中，一种低成本且工业上可扩展的石墨烯纳米流体添加剂 (GNA) 被加入到碳纤维增强水泥砂浆 (CFRCM) 中以增强其功能。结果表明，碳纤维和GNA的协同作用显着改善了水泥砂浆的多项性能。对于用 GNA 修改的 CFRCM (G-CFRCM)，抗弯和抗压强度的最大增加分别为 101% 和 126%，远大于对照的分别为 25% 和 45%，并且G-CFRCM 的热导率和电导率的最大增加分别为 36% 和 68%，远大于对照，分别为 27% 和 19%。此外，相应的使用寿命令人惊讶地增加与对照相比，G-CFRCM 的阴极保护系统增加了 200% 以上，表明这种新型复合材料非常适用于高效阴极保护系统中的应用。
