摘要
通过在水灰比一定的情况下,探讨了高石粉含量机制砂取代天然砂的不同掺量对预拌混凝土性能各方面的影响,结果表明高石粉含量机制砂取代部分天然砂在工程应用中是可行的,并能有效地改善和提高混凝土性能。
Instead of natural sand, effects of the high aggregate micro fines （AMF） contents of manufactured fine aggregate （MFA） on perfor- mances of ready-mixed concrete （RMC） are discussed with the same water-cement ratio.The results showed that it is feasible in engineering applications using portion manufactured fine aggregate of high aggregate micro fines contents to prepared ready-mixed concrete and performances of ready-mixed concrete are effectively improved and enhanced.
