Abstract
It is well known that the Born approximation technique is highly effective under weak scattering conditions. In the paper, a cement paste cylindrical specimen with complex flaw is prepared and ultrasonic measurements are carried out by experimental means. The measurement area is restricted in the plane perpendicular to the axis of cylindrical specimen. The measured wave data are fed into the approximate technique formula—the inversion method and cross-sectional image is obtained. We find that good results have been obtained for strong scattering void flaws such as complex flaw in cement paste cylindrical specimen
