Concrete is the material most produced by humanity. Its popularity is mainly based on its low
production cost and great structural design flexibility. Its operational and ambient loadings …

This work studies the use of ultrasonic imaging as an evaluation tool in concrete subjected
to freeze–thaw (F–T) cycles. To evaluate the damage in this deterioration process, ultrasonic …

Ultrasonic tomography is a non-destructive method that enables the map** of an internal
section of a structure from multiple projections for the identification of discontinuities and/or …

The ultrasonic pulse velocity method is a nondestructive test commonly used for the
determination of the elastic properties of materials and verification of non-homogeneities …

In order to evaluate the safety of concrete structures with the initial defect, the meso-scale
mechanical characteristics needed to be studied. The uniaxial loading failure process of …

The development of attenuation tomography for concrete is discussed. Fundamental
ultrasonic measurements of cubic specimens and numerical simulations of wave motion …

The main challenge faced by the conventional delay and sum (DAS) damage imaging
method for concrete is that the spatial resolution will be degraded when using few …

This paper presents an analytical model for calculation of corrosion induced stress field and
cracking time of concrete cover with initial defects in a reinforced concrete. In the proposed …

In this paper, a damage imaging method for 2-D concrete structures is proposed by
employing embedded tubular piezoceramic transducers. The proposed method can image …

One of the major reasons of deterioration in reinforced concrete structures is cracking of the
concrete cover. In contrast to bulk waves, ultrasonic Rayleigh waves are more sensitive to …
