The application of gangue concrete can be an effective method to solve the massive gangue heap and shortage of raw materials of concrete by replacing the gravel and river sand with crushed gangue. An Acoustic emission (AE) is one of the non-destructive testing methods that can be used for damage detection of the gangue concrete structure.

The incoming AE signals are processed in terms of the two parameters Distress® which is a measure of the transient activity on the detected signal (the clicks and crunches) and dB Level is a measure of the overall signal level. Characteristics of these two parameters are as follows: Distress® Distress mode provides an early warning of problems with rotating machinery vibration.
