Abstract: The research presented in this paper analyses the possibilities of acousto-ultrasonic (AU)
method in monitoring of hardening process in concrete from the time when concrete is in
plastic state. The measuring system which enables continuous acquisition of the transmitted
waveform, is presented and its performance is evaluated through an experimental
investigation. Analysis was performed on concrete mixtures made with different w/c ratios
(0.4, 0.5 and 0.65) and two cement types: CEM I 42,5 R and CEM III/B 32,5. Simultaneously
with the AU method compressive strength development was evaluated through destructive
testing of concrete cubes. It was found that a strong linear correlation exist between the
amplitude of the waveform transmitted through the concrete sample and the compressive
strength development.
