“…Recently developed acoustic techniques, used for evaluation of concrete properties, have investigated various nonlinear ultrasonic techniques such as harmonic generation [12], wave mixing [13] and diffuse field techniques [14][15][16][17][18][19][20]. The use of nonlinear ultrasonics for concrete inspection is attractive due to the high nonlinearity of the concrete and very high sensitivity of the nonlinear ultrasonics to various types of damage.…”

Comparative studies of nondestructive evaluation methods have shown that nonlinear ultrasonic techniques are more sensitive than conventional linear methods to changes in material microstructure and the associated small-scale damage. Many of the material degradation processes such as carbonation in concrete, corrosion in metals, etc., initiate at the surface. In such cases, ultrasonic Rayleigh surface waves are especially appropriate for detection and characterization of damage since their energy is concentrated in the top layer of the test object. For the civil engineering infrastructure, only a limited number of field applicable nonlinear ultrasonic techniques have been introduced. In this paper a nonlinear ultrasonic measurement technique based on the use of Rayleigh waves is developed and used to characterize carbonation in concrete samples. This work develops a collinear mixing technique for concrete structures. Wedge transducer is used for the generation and an accelerometer for the detection of the fundamental and nonlinearity modulated ultrasonic signal components. The measurements are made by varying the input voltage and along the propagation distance. The slope of the normalized modulation amplitudes is taken as the nonlinearity parameter. Concrete samples with two different levels of damage are examined, and the difference of the two fundamental frequencies is used to quantify damage state.

“…In Geophysics CWI has been used for more than 30 years, for instance to monitor structural changes in faults [10], volcanoes [11], landslides [12]. In NDE, applications are recent and concern mainly the detection of damage apparition and/or the monitoring of damage evolution [4,5,13].…”
