Originální abstrakt

This paper reports the results of measurements by Impact-echo method on two applications in civil engineering. The results are obtained in the laboratory during process in the degradation of concrete samples by corrosion caused by the action of chlorides and the degradation of composite materials based on cement by high-temperature (in the temperatures range from 200 °C to 1200 °C). The results of non-destructive testing of such samples by acoustic methods confirmed the differences in the structure of mortar specimens. A significant decrease of the absorbed frequencies was observed depending on the temperature. A shift of the dominant frequency to a lower value is a key indication of the presence of the flaw.

Klíčová slova
