Testing Post-Tensioning Strand 2

[dik]

Is there any electronic/ultrasonic means of testing the condition of existing strand?

dik,

The title is:

Non-contact ultrasonic imaging for post-tensioned bridges to investigate corrosion and void status.

I have not dug into the topic, so I don't know how useful it will be if at all.

We had a sales rep come into our office recently to show us some useful pieces of equipment for testing concrete. You may want to try this product

http://www.proceq.com/index.php?id=38&pqr=2&setpqr=1&L=0

for determining corrosion of reinforce/strand. There is also another machine on the market which taps the concrete and then by sonar scanning the vibrations it can determine whether there are any voids, honeycombing or cracks in the concrete. I didn't catch the name of the machine.
