THE CONCRETE CONSTRUCTIONS EXPERIMENTAL DIAGNOSTICS BASEDON THE ACOUSTIC IMPACT-METHOD
Keywords:
speed of sound, concrete, the impact method.Abstract
In this paper the features of concrete structures diagnostic by using the audio low-frequency oscillations are described. The existence of modal resonances in samples of a parallelepiped form was confirmed experimentally. An algorithm for extracting information components for determining the propagation velocity of acoustic vibrations and Young's modulus is proposed, which makes it possible to facilitate the search for resonant frequencies in planar structures.
