▎ 摘　　要

NOVELTY - Ammonium salt-graphene composite excitant comprises 20-35 wt.% ammonium chloride, 35-65 wt.% ammonium bicarbonate and 15-30 wt.% ammonium sulfate, where the graphene ratio of ammonium salts to graphite alkene is 10-15:1. USE - The ammonium salt-graphene composite excitant is useful for doped steel slag material which is useful in concrete. ADVANTAGE - The method utilizes easily available raw materials, is simple and economical, has good compression resistance, flexural resistance and stability, harmless, and does not generate any waste gas or waste liquid, and is suitable for large-scale industrial production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a steel slag material doped with ammonium salt-graphene composite excitant; and a preparation method of the steel slag material doped with ammonium salt-graphene composite excitant.
