| 摘 要： | 本文通过对机制砂性能特点的研究，研究了机制砂混凝土配合比的设计原则。通过分析石粉含量对机制砂砂高性能混凝土在工作性和力学性能上的影响，确定石粉含量的范同；通过对机制砂和天然砂混凝土性能的对比试验，结果表明机制砂砂完全可以替代天然砂配制混凝土。

| Abstract: | this paper on the performance characteristics of the machine-made sand, research on machine-made sand concrete mixture ratio design principles. Through the analysis of sand-stone powder content on machine-made sand high performance concrete on workability and mechanical properties of impact, determine the scope of stone powder content through comparative test of machine-made sand and natural properties of concrete, results showed that sand can replace natural sand concrete mixing. |
