【摘要】 研究了几种稀土贫矿对水泥熟料性能的影响.结果表明,在生料中添加适量稀土贪矿,可显著提高水泥熟料强度;不同稀土贫矿对水泥熟料性能的影响互不相同,其差异既与贫矿中的稀土含量及稀土组成有关,也与贫矿中含有的其它异组分种类及含量有关,是稀土贫矿各种性质的综合反映.更多还原

【Abstract】 The influences of several lean rare-earth ores on the properties of cement clinker are studied in this paper. Results indicate that the paste strength of the cement clinker can be remarkably increased by adding a proper amount of lean rare-earth ores to raw meal, and that the different lean rare-earth ores have different effects on the clinker properties. These differences are related not only to the contents and the compositions of the rare-earth oxides in the lean ores, but also to the varieties and the contents of the extra-components existing in the lean ores, which are the comprehensive effect of all the characteristics of the lean ores.更多还原
