粗骨料颗粒粒级对混凝土质量的影响

The Effects of Granule Size Fraction of Coarse Aggregate on Concrete Quality

随着科学技术的发展,混凝土工程基本实现了机械化或半机械化施工,这对混凝土用原材料质量标准也提出了较高要求。各种原材料对混凝土质量影响是不同的,但粗骨料颗粒粒级对混凝土质量的影响在工程施工中没有得到足够重视。针对这种问题,通过对粗骨料不同粒级掺配成的连续粒级进行试验分析,总结出了粗骨料的最大料级组配方法,可作为混凝土施工质量控制的参考资料。

With the development of science and technology, concrete work has almost achieved mechanized or semi-mechanized construction which produces higher requirements for the quality standard of raw materials for concrete. Although each raw material has its own effect on concrete quality, effects of coarse aggregate granule size fraction on concrete quality does not draw enough attention in the process of construction. In this regard, the author offers scientific data as reference material for quality control of concrete construction by experimental analysis of consecutive ones which are compounded by different size fractions.
