摘　　要：研究了采用超量取代法配制大掺量粉煤灰混凝土的工程应用技术.从混凝土配合比设计、施工质量控制等几个方面着手进行了分析研究,并对大掺量粉煤灰混凝土的和易性、强度、抗渗性方面等进行了检验,实践证明:通过控制较低的水灰比、掺加高效减水剂以及严格施工质量管理,大掺量粉煤灰混凝土在工程应用技术上是切实可行的.In this paper,the engineering application research on using super- substitute technique to prepare concrete added with high - volume fly ash was reported. We analyzed several aspects such as the designation of concrete composition,the quality control of construction. And we have tested the fluidity,the strengths and anti - permeation capability of the fly ash concrete. The results showed that it was feasible that the high - volume fly ash was compounded into concrete through lower w/c,the addition of admixture and the quality control on engineering application technique.
