【摘要】：鎢尾礦作為生產(chǎn)水泥的原料之一,既可以有效利用資源,又可以緩解水泥混合材供應緊張的局面。以湖南某鎢尾礦為研究對象,采用機械及化學的方法對鎢尾礦進行活化,并考察不同摻合量對水泥膠砂強度的影響。研究結果表明,采用磨礦方式對鎢尾礦進行活化時磨礦細度對水泥膠砂的活性指數(shù)影響不明顯;選用Ca O作激發(fā)劑可改善水泥膠砂的活性,活性指數(shù)達到67.65%。經(jīng)活化后的鎢尾礦摻合量為20%時,所制得的水泥滿足PO.42.5水泥的要求,可用于混凝土澆灌。
[Abstract]:As one of the raw materials for cement production, tungsten tailings can not only utilize resources effectively, but also alleviate the shortage of cement mixture supply. Taking a tungsten tailings in Hunan as the research object, the tungsten tailings were activated by mechanical and chemical methods, and the influence of different admixtures on the strength of cement mortar was investigated. The results show that the grinding fineness has no obvious effect on the activity index of cement mortar when the tungsten tailings are activated by grinding, and the activity of cement sand can be improved by using Cao as activator, and the activity index reaches 67.65. When the content of activated tungsten tailings is 20%, the cement can be used for pouring concrete because it can meet the requirement of PO.42.5 cement.
