Abstract
The article presents the main results of acoustic emission monitoring of concrete and fibro-concrete at an early age. The main characteristics of acoustic signals arising in a concrete mixture during the structuring of concrete with and without structural reinforcement are presented. In the course of the study, the influence of reinforcement on the processes of acoustic signal extraction during the formation of concrete samples was determined. The physico-chemical processes occurring inside the concrete mixture, associated with internal structural changes and, as a con-sequence, hydration stages, are interconnected with acoustic emission, which is sensitive to the capture of numerous elastic wave signals during the formation of the structure under various conditions

Abstract
The essence of the proposed methodology for monitoring the kinetics of damage to a deformed material is to establish a correspondence between micro-, meso-, and macrodamage, and the acoustic emission pulses generated in this case. During the loading process of a product, the recorded pulses are divided into pulse flows of low (H), middle (C), and high (B) energy levels, corresponding to the energy of destruction of structural bonds. By calculating the current values of the partial content of acoustic emission pulses in the H, C, and B clusters generated by micro-, meso-, and macrodamage, and comparing them with the threshold ones established during destruction, the load-bearing capacity current level of a product during loading is determined. Application of the developed methodology for identifying zones of developing damage and assessing the load-bearing capacity of the current state of stringers under loading conditions during interlayer shear tests is considered
