Abstract

Abstract

Seven concrete samples of di fferent cor rosion degrees are gained by direct-current test. AE signal collect system is adopted to detect bond damage process of these samples. Several tests are conducted before detecting as follow: through lead-breaking and simulant loadi ng tests, reasonable value of threshold which can efficiently insulate noise is gained; through lead-breaking tests, time parameters (PDT HDT HLT) which fit concrete samples are ob tained. Kaiser effect in the beginning of bond damage is found through analysing the events during bond damage process.
