Carbonation assessment in concrete by nonlinear ultrasound
Cement and Concrete Research, 2011 The carbonation process results in a change in the elastic properties of concrete, resulting in a variation of standard acoustic indicators such as wave speed. However, this evolution is too low to ensure an efficient carbonation assessment. The present communication focuses on the feasibility of carbonation assessment in concrete by applying Nonlinear

Response of bubbles to diagnotic ultrasound:a unifying theoretical approach [PDF]
, 1998 The scattering of ultrasound from bubbles of $\sim 1~\mu$m radius, such as used in contrast enhancers for ultrasound diagnostics, is studied. We show that sound scattering and ``active'' emission of sound from oscillating bubbles are not contradictory ...

The Variation of Precipitated Phase Investigated with the Usage of Nonlinear Ultrasonic Technique
Archives of Acoustics, 2021 It is well known that nonlinear ultrasound is sensitive to some microstructural characteristics in material. This paper investigates the dependence of the nonlinear ultrasonic characteristic on Al-Cu precipitation in heat-treated 2219-T6 aluminum alloy ...
