The Setting of Acoustic Emission Detecting Parameters in Concrete Structure
In order to solve the problem that the choice of acoustic emission (AE) parameters in concrete detection are determined only by experience
several tests were conducted. Through lead-breaking and stimulant loading tests
the reasonable value of threshold at which noise can be efficiently insulated was obtained. Through lead-breaking tests
time parameters (PDT
HDT
HLT) which fit concrete samples were obtained. The velocity and attenuation of AE signals in concrete also were measured through lead-breaking tests. This method of ascertaining detection parameters by testing is practical for AE detection in concrete structures.
