(57) A preparation method for an efficient and environment-friendly composite steel slag activating agent. The composite steel slag activating agent is prepared from the following raw materials in parts by mass: 0.2-0,4 parts of a polyol amine, 1-2 parts of a polyol, 0.4-0.6 parts of sodium acetate, 0.1-0.3 parts of graphene, and 0.2-0.6 parts of dihydrate gypsum. The raw materials, in parts by mass, are mixed at room temperature, and are mechanically stirred for 10 minutes to obtain the composite steel slag activating agent. The prepared composite steel slag activating agent can realize the rational utilization of a large amount of a waste steel slag material, and can improve the activity index and stability of the steel slag material after being mixed with cement, and the preparation method therefor is simple and efficient, is suitable for industrial production and is beneficial to reducing the consumption of clinker and inhibiting the emission of carbon dioxide.
