摘要
以芙蓉江大桥的索塔C50机制砂混凝土为研究背景,开展混凝土用复合掺合料研究。复合沸石粉掺合料具有多孔结构特征和典型的二次水化反应特征,净浆和砂浆的研究结果显示复合沸石粉掺合料将有利于索塔机制砂混凝土的施工工作性能。
Based on C50 manufactured-sand concrete in the cable tower of Furongjiang Bridge,the study on the compound mineral admixture of concrete is performed. Compound zeolite powder admixture has the characteristics of porous structure and typical secondary hydration. The study on paste and mortar shows that the compound zeolite powder admixture benefits the performance of manufactured-sand concrete for cable tower.
