The invention discloses an optimized magnesium slag-based cementing material and a preparation method thereof. The optimized magnesium slag-based cementing material comprises optimized magnesium slag, and the optimized magnesium slag is magnesium slag obtained after modified magnesium slag is subjected to natural aging or hot casting treatment; the modified magnesium slag is magnesium slag obtained after activity maintaining and stability maintaining treatment is conducted on magnesium slag generated by Pidgeon magnesium smelting; the preparation method of the optimized magnesium slag-based cementing material comprises the following steps: obtaining modified magnesium slag in a magnesium smelting plant, and placing the modified magnesium slag in a slag field for natural aging or hot casting treatment to obtain an optimized magnesium slag raw material; and carrying out coarse crushing and fine crushing pretreatment on the optimized magnesium slag raw material to obtain an optimized magnesium slag material. The optimized magnesium slag-based cementing material provided by the invention can completely replace high-cost cement, greatly reduces the cost of the cementing material, provides a new utilization approach for solid waste treatment in two large pillar industries of coal chemical industry and magnesium smelting, and solves the problems of long setting time and low consolidation strength in the middle and early periods of the magnesium slag cementing material.
本发明公开了一种优化镁渣基胶凝材料及其制备方法，所述优化镁渣基胶凝材料包括优化镁渣，所述优化镁渣为将改性镁渣进行自然陈化或热浇处理后的镁渣，所述改性镁渣为对皮江法炼镁产生的镁渣进行活性保持和稳定性保持处理后的镁渣；所述优化镁渣基胶凝材料的制备方法包括在镁冶炼厂获得改性镁渣并放置于渣场自然陈化或热浇处理，得到优化镁渣原料；对优化镁渣原料进行粗碎和细碎的预处理，得到优化镁渣料的步骤。本发明提供了一种能够完全替代高成本的水泥、大幅降低胶凝材料的成本、为煤化工和炼镁两大支柱行业的固废处置提供了一个新的利用途径的优化镁渣基胶凝材料，解决了镁渣胶凝材料凝结时间长和中前期固结强度低的问题。
