Ferronickel slag-based magnesium oxychloride cement and preparation method thereof
The invention provides ferronickel slag-based magnesium oxychloride cement and a preparation method thereof, the ferronickel slag-based magnesium oxychloride cement comprises the following components in parts by weight: 100 parts of ferronickel slag powder, 70 parts of hydrochloric acid, 98-122 parts of light calcined magnesia powder and 21-41 parts of water, the ferronickel slag powder is blast furnace ferronickel slag, and the ferronickel slag and hydrochloric acid reaction mixture replaces magnesium chloride powder to prepare the magnesium oxychloride cement. The problems of large stacking amount and low utilization rate of the ferronickel slag are greatly relieved, a method for treating the ferronickel slag is found, and the ferronickel slag-based magnesium oxychloride cement is excellent in compressive strength and breaking strength, higher in softening coefficient compared with conventional magnesium oxychloride cement, simple in preparation process and capable of being used for road repair and preparation of fireproof plates.
本发明提供了一种镍铁渣基氯氧镁水泥及制备方法，包括以下各组分：以重量份数计量，镍铁渣粉100份，盐酸70份，轻烧氧化镁粉98～122份，水21～41份，镍铁渣粉为高炉镍铁渣，将镍铁渣与盐酸反应混合物替代氯化镁粉来制备氯氧镁水泥，这极大缓解了镍铁渣堆存量大和利用率低的问题，找到一种处理镍铁渣的方法，本发明的镍铁渣基氯氧镁水泥抗压强度与抗折强度较优，软化系数比常规氯氧镁水泥较高，制备工艺简单，可用于道路修补与制备防火板。
