- Abstract
In order to observe the feature of split failure process of aggregate-mortar interface with a view to analyze and understand its damage mechanism, the whole split damage processes of interface specimens for granite-mortar were monitored by full-digital acoustic emission(AE) acquisition system. On the basis of the statistics analysis of AE signals associated with interface damage processes comprehensively, typical AE characteristics were summed up from the aspects of accumulation characteristics of AE signals, time history scatter plots of single AE parameter; and distribution analysis of combined AE parameters. The research results may be recommended for further recognition of physical mechanism of concrete damage processes, and for a deeper understanding of aggregate-mortar interfacial damage mechanism.
