制备了不同氧化石墨烯掺量的6组边长为100 mm的C30立方体混凝土试块，通过单轴抗压声发射试验来研究不同掺量的氧化石墨烯对混凝土力学性能和声发射参数（幅值、振铃计数、频率）的影响规律。结果表明：随着氧化石墨烯掺量的增加，混凝土各个龄期的抗压强度依次增大，混凝土的破坏形态整体性较好，混凝土的声发射频率范围逐渐加宽，混凝土的优势频率越来越大，并可根据声发射振铃计数率将混凝土的破坏阶段划分为5个阶段。

Six groups of C30 concrete cubes made of different dosage of graphene oxide were cast. The size of the cubes are all of 100 mm×100 mm×100mm. The uniaxial compressive test was carried out to study the effect of different dosage of graphene oxide on concrete mechanics performance and on acoustic emission parameters (amplitude, ringing counting, frequency). The results show that with the increase of the content of graphene oxide, the compressive strength of the concrete was increased at all ages, the destruction pattern of concrete was getting better, the acoustic emission was increasing, and the destruction stage of concrete was divided into five stages according to the ringing count rate.
