摘　　要：为了充分利用高镁石灰石和高硫煤资源,本文从生料的易烧性、熟料矿物的形成状况以及熟料性能入手,运用化学分析、X射线衍射、岩相分析等测试手段,研究了SO3对高镁硅酸盐水泥熟料组成和性能的影响。研究表明,当熟料中MgO含量较高时,通过控制熟料中SO3/MgO比,能够生产出性能优良的高镁硅酸盐水泥熟料。In order to make full use of high-magnesia limestone and high-sulfur coal resources, the effect of SO3 on composition and properties of high-MgO Portland cement clinker were studied by chemical analysis, X-ray diffraction, petrographic analysis and other testing methods from the aspect of the burnability of raw meal, the formation of clinker mineral and properties of the clinker. The results indicated that the excellent performance of high-MgO Portland cement clinker could be produced by means of rational control of the SO3/MgO ratio.
