NOVEL MATERIALS USEFUL FOR RADIOGRAPHIC IMAGING OF CONSTRUCTION MATERIALS AND METHODS USING SAME

摘要

The invention includes compositions that are useful for improving contrast in radiographic images. In certain embodiments, the compositions of the invention may be used in cementitious materials, thus allowing the analysis of grouts located around tendons and tendon anchorage regions around steel post-tensioning strands. The invention further includes methods of performing radiographic inspection using the compositions of the invention.

主权项

1. A composition comprising a construction material and at least one photon attenuation inclusion (PAI) particle, wherein for at least one X-ray radiation level the radiation attenuation coefficient of the composition is at least 5% higher than the radiation attenuation coefficient of the composition in the absence of the at least one PAI particle.
