Superfine iron-based carbon-free cementing material as well as preparation method and application thereof
The invention relates to a superfine iron-based carbon-free cementing material as well as a preparation method and application thereof. The superfine iron-based carbon-free cementing material comprises the following components in parts by weight: 60-120 parts of an exciting agent with a specific surface area of greater than 700 m<2>/kg, 5-15 parts of sulfur fixation ash or fly ash and 8 parts by weight of other auxiliary agents, wherein the exciting agent comprises, by weight, 30-70 parts of iron tailings and 30-50 parts of S95 mineral powder which are ground to obtain superfine mineral powder with the specific surface area of greater than 700 m<2>/kg; and the other auxiliary agents comprise an active agent, a binding agent, a grinding aid and a gelling agent.
本发明涉及一种超细铁基无碳胶凝材料及其制备方法及其应用，包括以下重量组分：激发剂：60‑120重量份；比表面积大于700m2/kg；固硫灰渣或粉煤灰：5—15重量份；其他助剂：8重量份；所述的激发剂包括：铁尾矿30—70重量份，S95矿粉30—50重量份研磨得到比表面积大于700m2/kg的超细矿粉；所述的其他助剂包括活性剂、结合剂、助磨剂、胶凝剂。
