This study is aimed to evaluate the transport properties of a cement composite incorporated with graphene oxide (GO). GO is a 2-dimensional nano material, enriched with reactive oxygen functional groups which made it as a suitable reactive material with cementitious materials. The GO-cement composite was prepared by adding GO in four different proportions such as 0.01%, 0.02%, 0.03%, and 0.04% by weight of cement. In the durability aspect water absorption, water sorptivity, resistance to acid attack, mechanical properties, thermal analysis, chloride migration coefficient, and chloride penetration depth were examined experimentally for GO-cement composite specimens and compared with plane cement composite specimens. Experimental results indicated that 14.5%, 30%, and 40.47% degradation in water absorption capacity, chloride migration coefficient, and chloride penetration depth of cement composite specimens with 0.03% addition of graphene oxide than normal cement composite specimens at 28 days of curing. Additionally, significant decrement in the sorptivity coefficient of cement composite was also achieved at 0.03% of GO addition. Mechanical properties were enhanced by 77.70% in flexural strength at 0.03% of GO addition and 47.61% in compressive strength at 0.04% of GO addition in cement composite at 28 days of curing. SEM analysis of the test samples exhibited the pore filled structure of the cement composites with GO addition. In addition, all GO-cement composite specimens exhibited greater resistance to an acidic environment and negligible loss in strength and weight was observed than normal cement composite specimens at 28 days immersion in 2% and 5% concentrations of both H₂SO₄ and HCl acidic solutions. Thermal resistance was increased in the terms of compressive strength in all GO-cement composite mixes gradually by increasing the concentration of GO content from 0.01% to 0.04% by weight of cement. It can be concluded that an effective improvement in transport properties of cement composite was achieved by the incorporation of graphene oxide nano material.

这项研究旨在评估掺入氧化石墨烯（GO）的水泥复合材料的运输性能。GO是一种二维纳米材料，富含活性氧官能团，使其成为适用于胶凝材料的活性材料。通过以四种不同的比例（例如水泥的0.01％，0.02％，0.03％和0.04％）添加GO来制备GO-水泥复合材料。在耐久性方面，对GO-水泥复合材料样品进行了实验检查，并与平面水泥复合材料样品进行了吸水率，吸水率，耐酸侵蚀性，机械性能，热分析，氯化物迁移系数和氯离子渗透深度的比较。实验结果表明，吸水率，氯化物迁移系数，降幅分别为14.5％，30％和40.47％，在固化28天时，添加0.03％氧化石墨烯的水泥复合材料试样的氯和氯离子渗透深度比普通水泥复合材料试样高。另外，在GO的添加量为0.03％时，水泥复合材料的吸附系数也显着降低。在固化28天时，水泥复合材料的机械性能在添加0.03％的GO时的弯曲强度提高了77.70％，在添加0.04％的复合材料时提高了47.61％的抗压强度。测试样品的SEM分析显示了添加GO的水泥复合材料的孔填充结构。此外，与普通水泥复合材料试样相比，在2％和5％的两种H浓度下浸泡28天，所有GO-水泥复合材料试样对酸性环境均表现出更大的抵抗力，并且强度和重量的损失可忽略不计。₂ SO ₄和HCl酸性溶液。通过将GO含量从水泥重量的0.01％增加到0.04％，在所有GO-水泥复合材料混合物中，随着抗压强度的提高，耐热性逐渐提高。可以得出结论，通过掺入氧化石墨烯纳米材料可以有效改善水泥复合材料的传输性能。
