Abstract
The initiation and development of microcracking in the process of solidification of concrete is studied according to the signals of acoustic emission. The correlation between the variations of the activity of a concrete mixture as a function of time and signals of acoustic emission is estimated for different periods of crystallization and hardening of concrete. Signals of acoustic emission were recorded with an N-338/4 high-speed recorder for the following working frequency range of the primary transducer: 100-500 kHz.
