| Abstract: | Acoustic emission is a widely used non-destructive testing technology. The application of acoustic emission in the study of mechanical behaviors of concrete is discussed. It focuses on the following aspects: the mechanism of concrete fracture, the damage location, the relationship between acoustic emission parameters and corrosion of reinforced concrete, the bond-slip behavior between rebar and concrete, behavior under fatigue load, the damage assessment of concrete structure and so on. The state of the art of researches is summarized. The problems to be solved in specific areas are discussed. |
