Abstract: Sand's fineness will influence the properties of concrete.This paper provides a critical review on the developmsnt of sand's fineness modulus formula and presents a modified formula which more accurately inaicates sand's fineness.
Key words: fine aggregate (sand), fineness, fineness-modulus
摘要： 本文介绍了细集料的粗细程度对砼技术性质的影响,并对长期延用的细度模数计算公式进行了修正,使得公式能更准确地反映细集出粗细程度这个特性。
关键词: 细集料, 粗细程度, 细度模数
