0引言我国自20世纪60年代便开始研究明矾石膨胀水泥,对煅烧明矾石的各种性能有深刻的研究。烧明矾渣是明矾石矿在煅烧明矾石后产生的废渣,其主要矿物为无定形硅、铝质矿物原料及少量的煅烧明矾石。我公司对安徽庐江烧明矾石废渣进行了分析研究,认为烧明矾渣是一种人工火山灰质混合材,可以代替本地产的粉煤灰、沸石(为保护环境已禁止开采)生产各品种等级的水泥,现对试验及生产应用作一简要的阐述。
0 Introduction China since the 1960s began to study alunite expansive cement, a variety of properties of calcined alunite have a profound study. Burning alum slag is the residue of alunite after calcination of alunite, the main minerals are amorphous silicon, aluminum mineral raw materials and a small amount of calcined alunite. Our company analysized Luzhou Alunite Waste Slag in Anhui Province. It is believed that Luoyang Alum Slag is an artificial pozzolanic material that can replace natively produced fly ash and zeolite (forbidden to protect the environment) to produce various grades Cement, is now a test and production applications for a brief description.
