This study is a basic research for estimating compressive strength of the high strength concrete by utilizing mechanical impedance method. Here, an experiment was performed to investigate the correlation and analysis about the actual compressive strength and the index value deduced by mechanical impedance method. Later, if an additional verification is carried out, it is determined to be possible to use a mechanical impedance method in the field.
