The paper presents the results of research on the development, manufacture, calibration and testing of acoustic emission (AE) system for non-destructive control and monitoring of the states of concrete structures of hydrotechnical structures. AE system contains four AE piezoelectric sensors, a processing unit, consisting of industrial computer, module of counters SCHM-16, software for collection and processing of AE data, keyboard and monitor. The piezoelectric detector of the AE system was calibrated in a frequency bands from 45 kHz to 75 kHz and from 95 kHz to 125 kHz according to the obtained AE spectrum of defect formation in a sample of monocrystalline silicon gamma-irradiated by ionizing radiation source 60Со with dose of ≥1·108 Rad. Laboratory tests of acoustic emission systems on concrete stands was conducted and the AE spectra of cracking were obtained. Using the AE system the threedimensional coordinates x, y, z of developing cracks in concrete blocks are determined.
