As an effective non-destructive test methods, acoustic emission technique has been widely appreciated at home and abroad. It is expected that the theoretical basis of acoustic emission technique has made a major breakthrough to the concrete in the acoustic emission parameters and to establish quantitative relationships between mechanical parameters.
