摘　　要：主要研究了粉煤灰、矿渣、龄期对混凝土和易性及抗压强度的影响,通过14组配合比试验,测试了不同阶段的抗压强度,结果表明:配合比为C4(双掺粉煤灰25%、矿渣8%)时,性能最佳。Studying the influence of fly ash, slag and age of concrete workability and compressive strength, we performed 14 sets of concrete mix- ture ratio experiments of testing the compressive strength of the various stages. The results showed that the mixture of C4 （ double mixing fly ash, slag, 25% and 8% ） , the best performance.
