Detection of chemical damage in concrete using ultrasound

S. Ould Naffa, Marc Goueygou, Bogdan Piwakowski, François Buyle-Bodin

This research deals with a non-destructive method for characterizing the degraded cover of concrete structures using high-frequency ultrasound (0.5–1 MHz). Although such a frequency range is unusual in civil engineering, it is well suited to the kind of defect to be detected, as it corresponds to a…

Assessment of broadhand ultrasonic attenuation measurements in inhomogeneous media

Marc Goueygou, Bogdan Piwakowski, S. Ould Naffa, François Buyle-Bodin

In this paper, we address the problem of evaluating the acoustic attenuation of “difficult” media, i.e. highly attenuating and scattering media. In a broadband, through transmission setup, the signals acquired from such media are characterized by a poor signal-to-noise ratio. Therefore, an accurate…
