摘要
粉煤灰混凝土超量取代配合比设计是以等强度对比为目的的计算方法 ,此法对粉煤灰初期的推广应用起到了非常重要的作用。在通过多年的粉煤灰应用实践后认为 ,现代粉煤灰混凝土配合比设计不应只强调等强度概念 ,而应同时考虑满足各种技术及经济指标 。
The aim of over mass for mass substitution of fly ash is to acquire the equivalent strength with the contrast concrete,and this method had played an important role in fly ash's initial use.Through many years practicing to the using of fly ash in concrete,it is realized that the equivalent strength conception between the concrete containing fly ash and the contrast concrete made with Portland cement alone should not be emphasized.For achieving the optimal mixture,the technological and economic benefits must be considered at the same time. \[
