TL;DR: In this paper, a new approach for characterizing material damage, using ultrasonic waves, is proposed, which can contribute greatly to the diagnosis of the degree of damage to a material, when combined with other traditional measures such as the attenuation of the material.

TL;DR: In this article, an exhaustive monitoring of an internal sulphate attack of Portland cement-based materials is addressed by means of physical, micro-structural and non-destructive tests, studying specimens with a low expansion rate.

TL;DR: If the attenuation of the material and the sensitivity of the measuring equipment allows the use of broadband signals, the combination of this kind of signal and suitable signal processing results in an optimal estimate of frequency-dependent attenuation with a minimum measurement time.

TL;DR: A novel and completely different approach to the problem of scattering material characterization: measuring the degree of predictability of the time series to demonstrate the ability of this technique to do classification.

TL;DR: In this article, a resonance-based algorithm is proposed to determine non-linear non-classical parameters through a single resonance frequency measurement, obtaining the expected sensitivity to internal damage.
