Abstract

This paper described a study on acoustic emission (AE) in the specimens of cement-based materials, especially concrete specimens. 1-3 cement-based piezoelectric composites that have good compatibility and broadband frequency, and they have been developed for health monitoring of concrete structures. It is suitable for 1-3 AE sensor to be embedded in concrete. The wave speed has a significant effect on the AE location results. The experiments between AE wave velocity and different distances condition under mortar and concrete two cement-based materials were conducted. The transducers were embedded in concrete, and pencil lead break test was implemented. It can be seen that the transducers embedded in concrete is more accurate and effective when compared with external test results. We could draw a conclusion that it was convenient for an embedded 1-3 AE transducer array to conduct accurate location monitoring of the development of cracks in concrete structure by online and in real-time inexpensively.
