摘要
本文研究了用煤矸石骨料代替天然骨料配制的透水混凝土的性能,采用正交试验方法分析了主要原材料和配比对煤矸石透水混凝土抗压强度与透水系数的影响,得出了影响强度和透水系数的主要因素是煤矸石骨料的粒径。
The performance of coal gangue pervious concrete is researched on the paper, effect of compression strength and permeation coefficient by raw materials and proportioning is analysed with orthogonal testing,coal gangue aggregate size is key factor to control compression strength and permeation coefficient.
