摘要
总结近年来国内外大掺量粉煤灰混凝土和特细砂混凝土的相关研究成果,结合嘉陵江航电枢纽工程,研究长龄期(90 d)特细砂粉煤灰混凝土的力学性能、耐久性和工作特性,对其在某船闸的应用进行了总结,指出了船闸工程大体积结构采用长龄期粉煤灰混凝土的可行性和优越性。
The research achievements about concrete with a large mixing amount of ultra-fine sand and fly-ash concrete home and abroad in recent years are summarized. Combining with Jialingjiang Hydro-power junction engineering, this paper studies the mechanical property, durability and working performance of 90 d- design-age ultra-fine sand and fly-ash concrete, and analyzes its application in a lock engineering, and demonstrates the feasibility and advantage of long design age fly-ash concrete when applied in large-volume structures of lock engineering.
