摘　　要：在对人工砂(主要为机制砂)的行业标准与技术规范进行深刻研究的基础之上,克服和借鉴已有测试方法的不足和应用局限,通过特定的测试手段从宏观和微观角度对石灰岩性机制砂及其石粉的基本特性进行了补充完善并给予了全新的解读,为机制砂的广泛应用提供了理论基础。There was a new interpretation on the basic characteristics of limestone manufactured sand and manufactured fine aggregate through some specific testing methods from macroscopical and microcosmic angle,which was based on the profound study of the manufactured sand technology norms and standards, and overcomes difficulties in limitations and flaws of test methods.This could be a theoretical foundation for manufactured sand to be widely used in engineering.
