摘要
结合纳(纳溪区)黔(川黔界)高速公路工程,在分析沿线机制砂颗粒级配、石粉含量和细度模数等三个基本性质及其关系的基础上,对现场机制砂生产提出具有实际意义的改进措施,可为机制砂的工程应用提供技术指导。
Combining NaQian expressway project,the author proposes the practical measures to manufactured sand production in field based on analyzing grain gradation,stone powder content and fineness modulus as well as revealing the relationship among them,which may guide to project applications of manufactured sand.
