摘要：研究了氧化石墨烯（GO）的掺量（0、0.042%、0.063%、0.084%、0.105%）对不同再生粗骨料取代率（0、40%、60%、80%、100%）再生混凝土试件抗压强度的影响，并拟合得到了掺GO再生混凝土的抗压强度与再生粗骨料取代率之间的关系表达式。结果表明：随着GO掺量的增加，试件的抗压强度呈先增大后减小的趋势，且当GO的掺量为0.063%时，试件的抗压强度达到最高；随着再生粗骨料取代率的增加，试件的抗压强度降低；ExpDec3指数函数可较为准确地表达掺GO再生混凝土的抗压强度与再生粗骨料取代率之间的关系。 Abstract: The influence of the content (0, 0.042%, 0.063%, 0.084%, 0.105%) of graphene oxide(GO) on the compressive strength of recycled concrete specimens with different replacement rates(0, 40%, 60%, 80%, 100%) of recycled coarse aggregates was studied, and the relationship expression between the compressive strength of recycled concrete with GO and the replacement rate of recycled coarse aggregate was fitted. The results show that with the increase of the content of GO, the compressive strength of the specimen shows a trend of first increasing and then decreasing, and the compressive strength of the specimen reaches the highest when the content of GO is 0.063%. As the replacement rate of recycled coarse aggregate increases, the compressive strength of the specimens decreases. The ExpDec3 exponential function can accurately express the relationship between the compressive strength of recycled concrete with GO and the replacement rate of recycled coarse aggregate.

Abstract: The influence of the content (0, 0.042%, 0.063%, 0.084%, 0.105%) of graphene oxide(GO) on the compressive strength of recycled concrete specimens with different replacement rates(0, 40%, 60%, 80%, 100%) of recycled coarse aggregates was studied, and the relationship expression between the compressive strength of recycled concrete with GO and the replacement rate of recycled coarse aggregate was fitted. The results show that with the increase of the content of GO, the compressive strength of the specimen shows a trend of first increasing and then decreasing, and the compressive strength of the specimen reaches the highest when the content of GO is 0.063%. As the replacement rate of recycled coarse aggregate increases, the compressive strength of the specimens decreases. The ExpDec3 exponential function can accurately express the relationship between the compressive strength of recycled concrete with GO and the replacement rate of recycled coarse aggregate.
