摘要
粗骨料是混凝土的主要组成部分之一,其性能对混凝土有着重要影响。在分析国内外相关研究成果的基础上,概括总结了粗骨料在混凝土中的作用,重点介绍了粗骨料种类、颗粒形状和表面特征、最大粒径和颗粒级配以及粗骨料在混凝土中的含量对混凝土性能的影响,最后得出了结论,为进一步提高混凝土性能提供参考依据。
Coarse aggregate is one of the main parts of concrete and its performance has great effect on cement. On the base of analyzing relevant research results home and aboard, the present paper summarizes the functions of coarse aggregate in concrete and introduces the types, particle shape and surface feature, maximum particle size and particle grading of coarse aggregate and the influence of its quantity on concrete. In the end, the paper arrives at a conclusion which provides reference to improve cement performance.
