- Abstract
- Results are presented of an investigation of the feasibility of applications of the Computerized Tomographic (CT) and the Compton Interaction Tomographic (CIT) processes to the nondestructive testing and evaluation of reinforced concrete components integral to many massive structures. The CT techniques were examined on a specially designed object incorporating various mass densities, cracks of varying dimensions, rebars, and air voids. It is concluded that these techniques are applicable to the nondestructive examination of massive structures. The CIT techniques were examined on a specially designed apparatus, with an aim to detect rebars and air voids embedded within a medium. The results of this study indicate the possibility of applications of this technique for the examinations of extended systems, such as highways and walls.
