Any experience in microwave moisture measurement in concrete

[Isatec]

I have been given a project looking at the moisture content of laid concrete of various types. I want to use a microwave technique of non destructive measurement rather than a conductive technique, do you think this is a sensible approach?

And if so do you know of any reliable, accurate device.

thanks in advance

Following is an Article from the ASTM Website. You will probably need membership to access. Also published in the 1994 Concrete & Aggregates journal. If you can run the journal down. I am trying to remember where I saw another article. I don't remember if this is 'in committee' for consideration as an ASTM method.
