Js. Popovics et Jl. Rose, A SURVEY OF DEVELOPMENTS IN ULTRASONIC NDE OF CONCRETE, IEEE transactions on ultrasonics, ferroelectrics, and frequency control, 41(1), 1994, pp. 140-143
The goal of this paper is to develop an understanding of the current s
tate of ultrasonic nondestructive evaluation in the concrete community
. Methods supplemental to the less than satisfactory proceedure specif
ied in ASTM C-597 are discussed. It is hoped that such an understandin
g, in conjuntion with a feeling for the nature of reinforced concrete
as a material, will promote research interest in this important field.
Following an introductory problem statement, a literature review conc
erning the existing use of stress waves for the nondestructive evaluat
ion of concrete is presented. An examination of current practice is of
fered. Next, new approaches are selected and reviewed from the current
literature. In all cases, these are approaches that have been success
ful in applications to advanced engineering materials other than concr
ete. Where appropriate, potential benefits and pitfalls of each new te
chnique, as applied to concrete, will be discussed.
