本文从不同粒径的砂石进行复配的角度出发,通过复配达到满足国家规范的技术指标要求。笔者分别探索出砂子和石子的复配方法,这两种方法通过简单的数学计算,快速确定砂石的不同品种之间的复配比例。找到了混合砂细度模数和碎石复配计算的简易方法,方便试验和生产。 This article from different particle size gravel complex point of view, through the compound to meet the national specifications of the technical requirements. The author explores the method of compounding sand and gravel, respectively. These two methods quickly determine the compounding ratio between different varieties of gravel through simple mathematical calculations. Found a mixed sand fineness modulus and gravel complex calculation of a simple method to facilitate the test and production.
