【摘要】 本文提出了在硅酸盐水泥熟料中规定方镁石最大允许含量以控制质量的可能性。探讨了影响方镁石最大允许含量的主要因素。试验表明,方镁石最大允许含量随方镁石粒度、水泥比面积和熟料中游离氧化钙而变化。在熟科中游离氧化钙较低时,水泥比面积固定的情况下,方镁石最大允许含量与方镁石粒度之间存在着双曲线类型的函数关系。更多还原

【Abstract】 In this paper, the possibility for controlling the quality of portland cement by defining the maximum periclase content of clinker and the main factors affecting on permissible periclase content are discussed. The testing results show that the maximum permissible periclase content depends upon the grain size of perielase crystals, the specific surface area of cement and the free lime content of clinker.The relation between permissible periclase content and grain size of periclase crystals is a function of hyperbolic form under conditions that the free lime content is kept within a certain limit and the specific surface area of cement is fixed。更多还原
