Seeing Through Concrete to Detect Corrosion

Seeing Through Concrete to Detect Corrosion
May-01-17
A new imaging technique that can ‘see’ through concrete could help teams detect corrosion in concrete-encased steel.

Developed by a team at the National Institute of Standards and Technology (NIST), the technique relies on terahertz radiation to detect early signs of corrosion. The method is an improvement over earlier versions, because it detects the actual rust compound instead of simply looking for physical changes, such as the thickness of the steel.

Matching rust compound to a frequency, is a variation used by edge doctors to tune a frequency to a known disease component ,thereby exciting it causing vibration that brings the bodies immune system into play or causes item seperation before DNA chain complete. Hench death from within.
