Not a good idea.
Wood changes dimension as the water content changes.
Because of this wood floors are not made of wooden tiles.
If they were then gaps would open when the floor dried and it might/would
buckle if it got too wet.

Now, that being said, IF you put down some sort of barrier so any moisture
in the concrete could not find it's way into the wood, and IF you used a
flexible grout (really a sealant) which had elastic properties sufficient to
allow the movement of the wood then it would be OK. I'm guessing that you
would end up with something like a bunch of wood stuck in a puddle of
sikaflex. Maintaining it with the combination of wood and flexible sealant
would be a problem - as would refinishing it since the sander would not like
the sealant at all.

My advice, stick to the traditional methods of installing wooden flooring.

om...
I want to make my own flooring tiles from wood and install them as you
would any other flooring tile. I would be intalling them on a solid
concrete subfloor. Is this possible? Would I be able to use grout, or
is there a special grouting material that I would use? Would I use
construction adhesive or thinset to lay the tiles? Would I seal them
with marine varnish, or would a urethane coating be sufficient?
Any advice on this topic would be appreciated. I like tile, love
wood, and hate parkay flooring. This idea seemed the best of both
worlds. Please help.
