摘要

该研究的目的是解释在混凝土中加入氧化石墨烯(GO)如何影响混凝土的抗压、拉伸和抗弯强度、透气性、吸附性、吸收率、抗冻性和导热性等性能参数。结果表明，在大多数情况下，氧化石墨烯的加入降低了材料的抗压强度。然而，已观察到所选参数的改善，例如，在0.005%的氧化石墨烯含量下，混凝土的抗折强度增加了7%，劈裂抗拉强度增加了6%。建议今后的研究方向是提高混凝土的流动性和改进均质化程序。

Addition of graphene oxide to increase the performance of concrete

The aim of the research was to explain how the addition of graphene oxide [GO] to concrete influences performance parameters such as compressive, tensile, and flexural strength, air permeability, sorptivity, absorbability, frost resistance, and thermal conductivity. It was found that the addition of GO in most cases decreased the compressive strength. Nevertheless, an improvement of selected parameters has been observed, eg, an increase in flexural strength by 7% and a split tensile strength by 6% for concrete with GO in the content of 0.005%. Concrete mixes with higher fluidity and improvement of homogenization procedures are suggested for future research areas.
