Ultrasound is considered as an effective nondestructive testing method. This review paper
discusses the potential of ultrasonic techniques for defect detection and fractures in …

As the cracking mode (tensile or shear) of a crack is related to the underlying physical
mechanisms, crack mode classification is a very useful method to identify the damage state …

Existing methods to detect cracks on underwater concrete components are mainly based on
sonar scanning and visual inspection. However, these methods are fundamentally limited by …

Ultrasonic noncontact methods of testing civil engineering materials in air, where both
transmission of waves into materials and reception of signals are contactless, are reviewed …

The main objective of this research is to investigate the applicability of diffuse ultrasound to
the evaluation of distributed micro-cracking damage in concrete. To simulate the micro …

We describe an approach that utilizes ultrasonic surface wave backscatter measurements to
characterize the volume content of relatively small distributed defects (microcrack networks) …

This study aimed at investigating two original topics on self-healing concrete, 1) the
prediction of long-term healing progress and 2) the evaluation of re-healing performance for …

The Internet of Things (IoT) paradigm is establishing itself as a technology to improve data
acquisition and information management in the construction field. It is consolidating as an …

We demonstrate the automated crack evaluation system for the rapid characterization of
internal/external concrete structures. Practical generation and detection of reliable and …

This study mainly aims to investigate the applicability of the combination of air-coupled
surface-wave and computer-vision techniques to the evaluation of self-healing in in situ …
