Review of Progress in Quantitative Nondestructive Evaluation
Center for Nondestructive Evaluation

Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.

This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract

The strength of concrete is controlled by three factors: strength of the matrix, strength of the aggregate, and strength of the bond between matrix and aggregate. It is well known that material interfaces play an important role in the overall mechanical behavior of bonded materials e.g concrete. Reflected and transmitted ultrasonic waves have been used to develop non-destructive ultrasonic techniques to examine the size and location of flaws and to provide measurements of the internal structure of concrete among other things. In the studies of elastic wave scattering by interfaces, it is generally assumed that the inclusion is perfectly bonded to the surrounding matrix material. It does, however, frequently happen that the bond is imperfect whereby reducing the stiffness and hence the strength of the material.
