<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>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 practices. <o:p></o:p></span></font></p>
