这为超掺粉煤灰混凝土的应用提供了理论参考。
This provided the theories foundation of the application of super fly ash concrete.
将磨细钢渣与优质粉煤灰复掺可以发挥超叠加效应，进一步改善混凝土性能；
When super-fine steel slag powder and high-quality fly ash were added into concrete together, the performance of concrete could be improved further due to the synergistic effect.
