▎ 摘  要

NOVELTY - Conductive concrete composition has fast curing cement as base material, and conductive concrete composite slurry that is based on the base material. The conductive concrete composite slurry has: 0.05-2 wt.% graphene, 0.5-3 wt.% graphene dispersant, 0-40 wt.% conductive filler and 15-30 wt.% water. The fast curing cement is phosphorus-magnesium cement. The graphene has at least one layer of redox graphene. The graphene dispersant has sodium dodecylbenzene sulfonate, sodium dodecyl sulfonate, N-methylpyrrole, sodium lignin sulfonate, pyrene acid, pyrenesulfonic acid, perylene acid, aniline trimer, aniline tetramer and/or polyvinylpyrrolidone. The conductive filler has carbon black, graphite, carbon fiber, carbon nano-tube and/or metal material. The metal material has copper powder, aluminum powder and/or steel fiber. USE - The composition is useful in electro-thermal heating and electro-thermal road field (claimed). ADVANTAGE - The composition: is capable of fast curing and forming; and has fast mass production of concrete product with good conductivity, high mechanical strength, stable resistivity and good durability, which improves the conductivity of the base material (resistivity can reach 10 Omega .cm) and accelerates the forming process (curing at room temperature within 30 minutes). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the conductive concrete composition.
