▎ 摘　　要

NOVELTY - Preparing efficient and environmentally friendly steel slag composite activator, comprises uniformly mixing 0.2-0.4 pts. wt. polyol amine, 1-2 pts. wt. polyol, 0.4-0.6 pts. wt. sodium acetate, 0.1-0.3 pts. wt. graphene, and 0.2-0.6 pts. wt. dihydrate gypsum at room temperature, and mechanically stirring for 10 minutes to obtain a steel slag composite activator. USE - The method is useful for preparing efficient and environmentally friendly steel slag composite activator. ADVANTAGE - The steel slag composite excitant can reasonably use large amount of waste steel slag material, after mixing with the cement, improving the activity index and stability. The preparation method is simple and efficient, it is suitable for industrial production, and is good for reducing the use amount of the clinker and discharging carbon dioxide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for method for using steel slag composite activator.
