Measurement of elastic wave velocity, concrete thickness, internal defects, delamination and crack depth

Basic principle

An elastic wave is generated by hitting the concrete surface with an impactor. The wave becomes multiple reflections as it reflects at the opposite surface, and it is called standing wave that corresponds to the thickness of concrete. iTECS can determine the thickness of a concrete by analyzing the standing wave. iTECS measures a velocity of vibration on concrete surface so the standing wave can be obtained more noticeable. Remarkable features of iTECS is to analyze the frequency of the waveform by MEM. Also, iTECS provides essential information to evaluate internal defects and thickness of concrete structures by analyzing temporal changes in frequency as a spectrogram. Besides, it will enable you to distinguish whether the vibration response of the structure is affected by the thickness or internal defects or delamination by analyzing the pattern of spectrum.
