Steel slag-red mud-electrolytic manganese slag mixture curing agent and steel slag-red mud-electrolytic manganese slag pavement base material
The invention provides a steel slag-red mud-electrolytic manganese slag mixture curing agent and a steel slag-red mud-electrolytic manganese slag pavement base material, and belongs to the field of building materials. Comprising the following components in percentage by mass: 1-3% of a heavy metal ion curing agent, 9-12% of an expanding agent, 7-9% of magnesium oxide, 14-16% of calcium chloride, 18-21% of silica fume, 19-22% of gypsum and 25-27% of a basic catalyst. According to the invention, the heavy metal ion curing agent is used for curing heavy metal elements (hexavalent chromium, mercury and vanadium) in the steel slag-red mud-electrolytic manganese slag mixture, so that the purpose of utilizing a large amount of steel slag, red mud and electrolytic manganese slag is achieved; the concrete has the characteristics of high strength, excellent water-resistant stability and small shrinkage, is widely applicable to steel slag, red mud and electrolytic manganese slag, solves the problem of heavy metal pollution, and has important economic and environmental benefits.
本发明提供了一种钢渣‑赤泥‑电解锰渣混合料固化剂和钢渣‑赤泥‑电解锰渣路面基层材料，属于建筑材料领域。包括以下质量百分比的组分：重金属离子固化剂1～3％，膨胀剂9～12％，氧化镁7～9％，氯化钙14～16％，硅灰18～21％，石膏19～22％和碱性催化剂25～27％。本发明利用重金属离子固化剂对钢渣‑赤泥‑电解锰渣混合料中重金属元素(六价铬、汞、钒)进行固化，达到钢渣、赤泥、电解锰渣大宗量利用的目的，其应用于制备钢渣‑赤泥‑电解锰渣路面基层材料，具有强度高、抗水稳定性能优异、收缩小的特点，对钢渣、赤泥、电解锰渣适用性广，且解决了重金属污染问题，具有重要的经济和环境效益。
