Abstract
We demonstrate that a scanning acoustic microscope (SAM) operating in the f requency range 100-400 MHz can detect cracks at the aggregate/paste interfa ce and subsurface cracks in aggregates with high sensitivity. A complete in terpretation of the obtained results has been made by combining high and lo w frequency acoustic microscopy, SEM, optical microscopy, and energy disper sive (X-ray) spectroscopy.
