低碱水泥生产途径的探讨

Approach to production method of low alkali cement

水泥中碱含量主要来自熟料，影响熟料减含量的主要因素是石灰石和粘土质原料中的碱含量。文章通过对石灰石和粘土质原料质量特征的分析，提出了生产低碱水泥的途径，并就旁路放风对降低熟料碱含量的影响作了探讨。

The alkali contained in cement comes mainly from clinker, and the major factors influencing the clinker alkali content are the alkali contents in limestone and clayey raw material. Through analysis tu the quality features of limestone and clayey raw material, this paper has proposed a method of preducing low alkall cement, and explores the effectof bypass to the reduction of alkali content in clinker.
