▎ 摘  要

NOVELTY - A graphene cement-based grouting material comprises 100 pts. wt. cement, 0-40 pts. wt. mineral mixture, 50-150 pts. wt. aggregate, 2-10 pts. wt. fine powder, 0.2-0.5 pts. wt. water reducing agent, 0.05-0.2 pts. wt. antifoaming agent, 5-10 pts. wt. expanding agent, 0.5-5 pts. wt. reducing agent, 0.1-0.5 pt. wt. rheological agent, and 0.1-10 pts. wt. graphite. USE - Graphene cement-based grouting material. ADVANTAGE - The grouting material has high compressive strength and durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene-cement base grouting material comprising weighing superfine powder and graphene, using high-speed flying with stirrer, uniformly stirring, preparing mixture of graphene and ultra-fine powder, putting mixture into mortar mixer, stirring cement, mineral mixture, aggregate, water reducing agent, antifoaming agent, expanding agent, shrinkage reducing agent, and rheological agent, stirring, and uniformly mixing with other components.
