摘要
通过正交试验设计对高性能粉煤灰混凝土的强度及抗渗性的影响因素进行分析。采用比较先进的有机溶剂渗透法准确、快速评价高性能粉煤灰混凝土的渗透性。加入适量粉煤灰(水泥质量的25%),有利于提高混凝土的后期强度,降低渗透性,进而改善耐久性。
This paper analyzes influential factors on the strength and impermeability of High Performance Fly Ash Concrete (HPFAC) by orthogonal experimental design and adopts advanced organic-solvent-penetrate way to evaluate the permeability of High Performance Fly Ash Concrete accurately and quickly. The results show that when adding appropriate volume of fly ash (cement volume's 25%),the late strength of High Performance Fly Ash Concrete is increased,and its permeability is decreased and further its durability is improved.
