▎ 摘　　要

NOVELTY - The concrete synergist comprises 20-30 pts. wt. graphene oxide, 10-15 pts. wt. amorphous carbon, 4-6 pts. wt. air entraining agent, and 100-120 pts. wt. water, where the particle diameter distribution of graphene oxide is 10-100 nm, and the particle diameter distribution of amorphous carbon is 50-200 nm. USE - Used as concrete synergist. ADVANTAGE - The concrete synergist has excellent adhesiveness between the graphene oxide and amorphous carbon particles. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of concrete synergist comprising weighing each component, mixing and ultrasonically dispersing in water.
