Effects of Aggregate Types on Acoustic Emission Characteristics of R/C Beams in Lap Splice

The aim of this study was to examine the emission of acoustic signals from three reinforced concrete beams at cracking and failure processes. Acoustic emission(AE) characteristics of reinforced concrete beams were investigated during the entire loading period. AE technique was used to evaluate the characteristics of damage process and the failure mechanism of reinforced concrete beam with natural and recycled aggregates. The influences of different aggregate in concrete on AE characteristics were investigated as well.
