Description

The porous, inhomogeneous, and attenuative nature of concrete requires the use of low frequency ultrasonic nondestructive methods for the purpose of condition assessment due to the disturbed wave characteristics in the medium. Current ultrasound techniques are limited by a small aperture width, resulting in minimal resolution and static directivity. In order to overcome such deficiencies, a novel low-frequency ultrasonic phased array has been developed and its feasibility was tested for the assessment of concrete and other cementitious materials.
