High-activity composite ferronickel slag cementing material and preparation method thereof
The invention discloses a high-activity composite ferronickel slag cementing material which comprises the following components in parts by mass: 3-5 parts of gypsum, 5-10 parts of quartz powder, 20-50parts of blast furnace ferronickel slag, 10-30 parts of submerged arc furnace ferronickel slag, 5-20 parts of steel slag, 0.3-0.8 part of composite excitant and 0.1-0.2 part of drag reducer. The composite excitant comprises at least three of alkali metal hydroxide, an alkali metal calcium source, sulfate and water glass. The utilization rate of ferronickel slag is increased, the gel performance is good and the production cost is reduced.
本发明公开的一种高活性复合镍铁渣胶凝材料，包括质量份数如下的组分：3‑5份石膏、5‑10份石英粉、20‑50份高炉镍铁渣、10‑30矿热炉镍铁渣、5‑20份钢渣、0.3‑0.8份复合激发剂、0.1‑0.2份减阻剂，所述复合激发剂包括碱金属氢氧化物、碱金属钙源、硫酸盐、水玻璃中的至少三种，提高镍铁渣使用率，凝胶性能好，降低生产成本。
