 note = {application/pdf, On the problems of mentainance and management for structures, there are two faces. One is as to the management of the function of structures and the other is as to the maintainance of materials. In the functional side, inicial conditions at the designing stages affect to the management of structures, and may be forced at times to be changed foundamentally. On the other hand, in the material side, it is an important subject how to grasp the change of material quality according with time progress and situation for common use. In this study, the latter face is focused. And so, it is the purpose of this study to construct a comparatively simple diagnosis system for materials by using non-distractive methods, such as the acoustic impact technique and the acoustic emission test. And at first, by using non-distractive method, the foundamental properties of mortar materials which are generally used for structures are discussed and some standards of the evaluation as to AE parameters are proposed., Bulletin of the University of Osaka Prefecture.
