Abstract: 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.
