摘　　要：为了研究氧化石墨烯对再生砂浆力学性能的影响,对掺加0%、0.02%、0.04%、0.06%氧化石墨烯的再生砂浆进行了抗折和抗压试验研究,并通过SEM扫描研究其微观结构。结果表明,在氧化石墨烯掺量高于0.04%时,再生砂浆的抗压强度和抗折强度提高明显,且氧化石墨烯掺量为0.06%时达到最大,氧化石墨烯掺量的增加有助于提高再生砂浆的力学性能,改善其微观结构。In order to study the effect of graphene oxide on the mechanical properties of recycled mortar,four levels of graphene oxide content 0%,0.02%,0.04% and 0.06%（by the cement quality percentage）are considered in mix proposition of recycled mortar,and the test of flexural and compressive strength of recycled mortar is carried out,and the microstructure is observed through SEM.The results show that when the content of graphene oxide is higher than 0.04%,the compressive strength and flexural strength of recycled mortar are increased obviously,and reach the maximum when the content is 0.06%.The increase of graphene oxide content helps to improve the mechanical properties and microstructure of recycled mortar.
