▎ 摘  要

NOVELTY - Conductive concrete material comprises 200-800 pts. wt. Portland cement, 500-1600 pts. wt. standard sand, 15-25 pts. wt. dispersant, 3-8 pts. wt. graphene alkyne nanomaterial and 250-350 pts. wt. mixed water. The graphite alkyne nanomaterial has particle diameter of 200 nm to 1 mu m. The standard sand has particle size of 0.25-0.5 mm. he dispersant is polyoxyethylene nonylphenyl ether as white waxy solid. The quality tolerance of: cement is plus minus 1%, standard sand is plus minus 1%, dispersant is plus minus 0.5%, graphene alkyne nanomaterial is plus minus 0.5% and mixed water is plus minus 1%. USE - Used as conductive concrete material. ADVANTAGE - The material has excellent conductivity, good intensity and good for actual engineering application of new conductive concrete, and obviously reduces resistivity of concrete material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing conductive concrete material, comprises (a) performing surface modification of graphene alkyne nanomaterials using polyoxyethylene phenyl phenyl ether as dispersing agent, completely dissolving the dispersing agent with the mixing water, adding graphene alkyne nanomaterials, and performing sonication to obtain uniformly dispersed graphite alkyne dispersion suspension, (b) accurately weighing raw materials according to the ratio, adding cement into a stirring pot, uniformly stirring, adding graphite alkyne dispersion suspension, stirring at high speed for 120-160 seconds, stirring at low speed for 70-100 seconds, vibrating and compacting the stirred graphite alkyne cement slurry casting mold, and (c) cleaning the sample, standard curing for 1 day, removing the mold, performing relevant performance tests after curing to the appropriate age in a standard environment, and curing at 20 plus minus 2 degrees C and relative humidity of greater than or equal to 95%.
