▎ 摘　　要

NOVELTY - Composite modified concrete, comprises silica fume, graphene oxide, water, cement, sand, crushed stone and water reducing agent, where the crushed stone is basalt crushed stone. USE - Composite modified concrete used in residential buildings, bridges and other municipal infrastructure. ADVANTAGE - The oxidation graphene silicon ash composite modified concrete has excellent mechanical performance and active functional group, has unique advantages in promoting cement hydration and the raw material is derived from graphite, so the cost is low, it has high-cost benefit, and has high production efficiency of the prefabricated building at the same time, the later strength and durability are greatly improved to improve the production quality of the building. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of composite modified concrete.
