Abstract
This study presents a use of the acoustic emission examination technique to determine the dimensions of the microcracked zone leading a macrocrack propagating in concrete. A critical analysis of the locating method is followed by a presentation of its application to conventional concrete, steel fibre concrete, and high-strength concrete.
