摘要：机制砂作为天然砂替代品，在颗粒形貌、石粉含量等质量指标上均不同于天然砂，因此，导致混凝土性能存在差异。本文在分析国内外标准规范的基础上，研究了不同规范中机制砂的定义及质量指标，叙述了机制砂质量指标对混凝土性能的影响，进而为机制砂的工程应用提出建议。 As a substitute for natural sand, manufactured sand is different from natural sand in quality indexes such as particle morphology and stone powder content, which will lead to differences in concrete performance. Based on the analysis of standards and specifications at home and abroad, the definition and quality index of manufactured sand in different specifications are studied. The influence of quality index of manufactured sand on performance of concrete is summarized, and some suggestion for engineering applications of manufactured sand are put forward.
