NOVELTY - Enhanced graphene conductive permeable concrete comprises 16-22 pts. wt. cement, 71-80 pts. wt. fine stone, 5.3-7.9 pts. wt. water, 1.8-2.3 pts. wt. steel slag powder, 0.32-0.51 pts. wt. water reducing agent, 0.21-0.55 pts. wt. graphene and 0.09-0.13 pts. wt. redispersible emulsion powder. USE - The enhanced graphene conductive permeable concrete is useful for northern road deicing. ADVANTAGE - The enhanced graphene conductive permeable concrete: has improved the strength and prolonged the service life; and reduces the electrical resistivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing enhanced graphene conductive permeable concrete comprising (i) adding PO42.5 Portland cement, steel slag powder and redispersible emulsion powder into mixing machine and uniformly mixing to obtain mixed permeable cementitious material, (ii) placing fine stone and mixed permeable cementitious material in a blender for dry mixing for 60-120 seconds, (iii) adding an aqueous conductive paste containing 0 graphene and water to mixer, and stirring for 120-200 seconds to obtain mixed enhanced graphene conductive permeable concrete, and (iv) introducing fresh concrete into the mold; tamping with psi 16 mm tamper and vibrating on the vibrating platform for 6-10 seconds to obtain final product.
