Thermal Resistivity of Concrete?

Thermal Resistivity of Concrete?

Thermal Resistivity of Concrete?

(OP)
Hello,
Electrical engineers sometimes need to calculate the heating effects of running multiple electrical feeders in concrete encased duct banks.  One of the most critical properties of the concrete used is the Thermal Resistivity, designated as "Rho" in most electrical code books.  The units for the thermal resistivity are in degrees C-cm/watt.  Do any of you concrete experts know if there is any published data for this property for different mixtures of concrete.  We would be most interested in a concrete with 3000 psi @ 28 days strength value.  That is as technical as we get with the concrete requirements, (well it's better than what we used to say:  "concrete shall be six sack mix"- isn't it?wink).
I appreciate any guidance you can offer.

Have a pleasant day/evening,
EEJaime
