ABSTRACT = {Ultrasonic non-destructive evaluation is an essential component of condition assessment of concrete. Conventionally, the use of ultrasonics is limited to
the study of velocity of sound through concrete. The velocity is qualitatively linked
to the condition of the concrete in service. However, sophistication in signal processing has led to the development of better ultrasonic techniques that can give
some quantitative estimates of the damage. This paper describes the use of the
transmitted ultrasonic energy to estimate the level of damage in concrete under
uniaxial compression. The experimental set up was designed to collect ultrasonic
signals between transducers at opposite ends of a concrete cube that was loaded
in compression. A specially designed software program allowed real time analysis of the signal – including calculation of transmitted energy, obtaining FFT, etc.
The methodology adopted in the study was able to differentiate the behaviour of
ordinary and high strength concrete in compression.},
