Abstract

The mineral admixtures mixed into concrete have important effects on concrete performance. The workability and mechanical properties of the concrete are studied with different dosages of admixtures, such as steel slag powder, blast furnace slag powder and fly ash. The results show that fly ash has more advantages in improving the performance of the concrete. When steel slag powder, blast furnace slag powder and fly ash, respectively, replace the amount of cement to 30%, 30%, 20%, the mechanical properties of the concrete are improved significantly.
