高炉矿渣微粉的开发与利用

The Development and Exploitaion of Blast Fumance Slag

我国冶金企业每年产生大量的高炉矿渣,这些矿渣不仅占用大量的耕地,而且污染环境;通过将高炉矿渣粉磨成比表面积为430m^2/kg及以上的矿渣微粉,其活性在碱性介质中得到充分发挥,可在混凝土中等量取代水泥20％～40％,既减小了环境污染,又大大的增加了经济效益。

Metallurgical enterprises in our country produce a large quantity of blast fumance slag annually. The slag not only takes up a large quantity of farmland, but also pollute the environment. By shattering the slag to powder, its activity is improved in the alkaline medium, and it can replace the cement in the concrete 20%-40%, this can reduce the pollution of the environment, and increase economic benefit consumedly.
