Lead-zinc smelting slag-based cementing material as well as preparation method and application thereof
The invention discloses a lead-zinc smelting slag-based cementing material as well as a preparation method and application thereof. The lead-zinc smelting slag-based cementing material comprises the following components in parts by mass: 45-75 parts of lead-zinc smelting slag, 8-30 parts of cement clinker, 0-7 parts of calcium chloride and 11-45 parts of an exciting agent, the exciting agent comprises silica fume, mirabilite and bauxite. The cementing material disclosed by the invention adopts the activator compounded by the silica fume, the mirabilite and the bauxite, the silica fume, the mirabilite and the bauxite have a synergistic effect, the activator disclosed by the invention effectively excites the activity of the lead-zinc smelting slag, and the 28d compressive strength of the excited lead-zinc smelting slag based cementing material is greater than or equal to 20MPa; the method can be used for development of low-cost ecological cementing materials and products thereof.
本发明公开了一种铅锌冶炼渣基胶凝材料及其制备方法和应用。一种铅锌冶炼渣基胶凝材料，包括以下质量份的组分：45‑75份铅锌冶炼渣、8‑30份水泥熟料、0‑7份氯化钙、11‑45份激发剂；激发剂包含硅灰、芒硝、铝矾土。本发明的胶凝材料采用硅灰、芒硝和铝矾土复配的激发剂，硅灰、芒硝和铝矾土三者之间存在协同作用，本发明的激发剂有效的激发了铅锌冶炼渣的活性，激发后的铅锌冶炼渣基胶凝材料的28d抗压强度≥20MPa，可以用于低成本生态胶凝材料及其制品开发。
