摘要: In this study, some experiments were conducted for different types of defects embedded in grout specimens. Based on the comparison between the actual condition of the defects and tomograms, the feasibility of acoustic emission tomography for defects visualization was investigated. Influences of inclusions, crack size and inclination, and infills were also studied. Experimental results indicated the location, geometry, and inclination of inclusions and cracks. It is concluded that a series of factors influence wave propagation and the …
