This is copy of a post to the Gingery group it may help.
I note that if you use concrete add some waterproof agent to it to prevent inherent moisture leaching to the steel body causing rust.

Subject: Vibration damping

Interesting post I ripped off the Chaski board (I steal all my best
ideas!)for application to Gingery machines:

"What I did notice was that the taig has an extrusion body filled
with what looks like cement. On top, is a dovetail steel bed much
like that of hardige. Martin of germany builds 30,000 dollar table
saws with a cement filled steel sandwhich structure. This structure
absorbs 6 times as much vibration as pure cast iron and cast iron
absorbs 10 times as much as rolled steel and aluminum. So I know the
taig will excel here." Posted by emchd on December 17, 00 at 20:34:4
