Investigations with reinforced concrete tomography
The reinforced concrete tomography (RCT) is a non-destructive technique that uses gamma rays to obtain diameters and positions of all steel bars in structural sections, even in cases of congested reinforcement, with an accuracy of +/- 1 and 5 mm, respectively. This is well beyond what is achievable with other current methods such as the Ground Penetrating Radar, Covermeter, Acoustic Emission or Ultrasound. In addition, because of its 'photographic' quality, RCT can be used to investigate steel corrosion and voids in reinforced concrete. This methodology has been successfully used in hundreds of structures including bridges, buildings, bank treasuries, industrial establishments, silos and monuments. In this paper results obtained from a few cases of special interest are presented: the investigation of defective grouting in ducts of a post-tensioned beam in Argentina's largest bridge; the study of underwater pillar sections at Ushuaia harbor; the detection of termite-produced cavities in a hidden wood structure of a XVII century chapel; and recent tests for the detection of corrosion in hinge deck bridges found in hundreds of locations on the UK trunk road and motorway network.
