▎ 摘　　要

NOVELTY - A thermal energy-transfer system comprises a thermally conductive concrete (102), in cured form and in the form of a structural article, a location of energy supply or demand that is physically isolated from, but in thermodynamic communication with, the thermally conductive concrete, and one or more pipes, tubes, capillaries, manifolding or other containment regions comprising thermal energy-transfer medium for transferring thermal energy between the structural article and location of energy supply or demand, configured for heating and/or cooling the location of energy supply or demand. The thermally conductive concrete has a compressive strength of more than 2500 psi, and comprises more than 5 to 35 vol.% carbon, one or more metals and/or conductive polymers, aggregate and cement. USE - Thermal energy-transfer system such as solar-energy collection system, grade beam, indoor radiant flooring system, structural wall or ceiling, bridge, roadway, driveway, parking lot, commercial aviation runway, military runway, grain silo, or pavers (all claimed). ADVANTAGE - The thermal energy-transfer system reduces or eliminates the large amount of washed gravel normally associated with soil stability, large amount of concrete, and large amount of steel reinforcement. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a grade beam. Grade beam (100) Embedded tubes (101) Thermally conductive concrete (102)
