Abstract

Abstract: Since the 1990s， cracking of concrete bridge has being a clearly trend，which directly threatening to the durability and security of bridge structures． This article collected relevant documents，then analyzed effects of fineness and composition of cement on the performance of concrete，and pointed out the differences between the current national cement standard and the performance requirements of concrete bridge． It also puts forward preliminary proposal for some parameters on fineness and composition of cement in bridge structures．

Key words: fineness and components of cement, concrete performance, concrete bridge

摘要： 在收集相关文献资料的基础上，分析了水泥细度与组成对混凝土性能的影响，指出现行国家水泥标准与桥梁结构混凝土性能要求方面的差异，初步建议了桥梁结构混凝土用水泥细度与组成成分参数指标。

关键词: 水泥细度与组成, 混凝土性能, 混凝土桥梁
