摘　　要：本文针对我国粉煤灰中适于作高性能混凝土活性掺和料的优质干排灰较少 ,大部分为低等级湿排粉煤灰的现状 ,用经过预激活处理的湿排粉煤灰作水泥混合材 ,并掺入高效减水剂、石灰石粉等外加剂 ,通过正交试验配制出 5 2 5R～ 6 2 5R高性能混凝土专用水泥。The authors of this paper aimed at the present state in which the high quality dry fly ash suitably to used as the active admixture of high performance concrete is small and most of it is low class wet fly ash,developed the class 525R～625R special cement for high performance concrete adopted pre activated wet fly ash used as addition of cement,as well as by adding superplasticizer and limestone powder etc.admixture by orthogonal experiments.
