本文在分析研究国外粉煤灰混凝土配合比设计的基础上,着重介绍了粉煤灰混凝土超量取代法配合比设计的基本原理和方法,并提出了用超量取代法进行配合比设计的具体步骤,还列举了配合比计算实例。
Based on the analysis of the mix proportion design of fly ash concrete in foreign countries, this paper focuses on the basic principles and methods of the mix proportion design of fly ash concrete with excess substitution, and proposes the specific design of the mix ratio with the excess substitution method. Steps are also listed as examples of mix ratio calculations.
