摘要
结合贵瓮高速公路特点,通过石粉含量、掺合料掺量两个因素,对贵阳地区机制砂混凝土配合比采用正交试验设计,定量分析粉煤灰掺量和石粉含量对混凝土各项性能的影响,配制出适用于工程实际使用的优良配合比。
According to the characteristics of Highway Guiyang-Weng＇an,based on the two factors of stone powder content and admixture content,orthogonal design was used to test the mix proportion of the manufactured sand concrete in Guiyang.The effects of fly ash content and stone powder content on the properties of concrete were quantitatively analyzed and the excellent mix proportion suitable for engineering application was worked out.
