Here is a great website that is all about concrete and nothing but concrete.

You might find an answer there.

Anyone know of a common and cheap procedure to add a material to a
concrete pour to drive up its conductivity from a common 1.6 to 1.7
W/m-K. We don't want to add rebar nor a wire mess. I'm thinking of
pulverized metal material that would not corrode within the conrete
reducing the strength, causing cracks/discoloration. I'd be
appreciative if anyone knew of any research or currently applied

With radiant tubing buried a further depth below the finished surface,
want to increase the dynamic response of the slab.
