▎ 摘  要

NOVELTY - Conductive cement composition comprises cement and a functionalized carbon composite. The functionalized carbon composite is a carbon material mixed with an aromatic ring compound having a functional group including at least one of 0.1-50 at.% nitrogen atom derived from functional group and an oxygen atom. USE - The cement composition is useful in preparing conductive concrete (claimed) for road pavement. ADVANTAGE - The cement composition: exhibits high electrical conductivity and thermal conductivity; and efficiently controls the icing of the road in economical way. The conductive concrete has an electrical conductivity of 10-7 to 10-2 S/cm, and a thermal conductivity of greater than or equal to 1.6 W/mK. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing cement composition, comprising preparing a functionalized carbon composite in which an aromatic ring compound having a functional group including nitrogen atom and oxygen atom and a carbon material are bonded, dispersing the functionalized carbon composite in a solvent to obtain functionalized carbon composite dispersion, and mixing the functionalized carbon composite dispersion with cement.
