EXPERIMENT MICROSEISMIC EVALUATION OF ARTIFICIALLY INDUCED DEFECTS ON STONEWORK. FRACTURE OF CONCRETE AND ROCK: RECENT DEVELOPMENTS. PAPERS PRESENTED AT THE INTERNATIONAL CONFERENCE, UNIVERSITY OF WALES, COLLEGE OF CARDIFF, SCHOOL OF ENGINEERING, SEPTEMBER 20-22, 1989

This paper examines a microseismic technique for detecting and analyzing internal fissures and flaws in the stone of historical and monumental buildings. In order to define an effective investigation procedure, an experimental program was developed, based on the creation of artificial defects (fissures, internal cavities, etc). The perturbations induced by these defects in the propagation of microseismic waves are analyzed, and some results are reported here. As cracks and other defects in monumental stone are frequently intruded by water or dirt, sometimes repaired by means of injections of mortars and resins, and more or less closed by stresses, consequent variations in microseismic parameters are also analysed.(A) For the covering abstract of the conference see IRRD 829348.
