Research on High Performance Concrete with Steel Slag and Blast Furnace Slag for High-grade Pavement

摘要

In this research, a new compound activator of steel slag and blast furnace slag powder was developed. On the basis, two mixture proportions of concrete with flexural strength of 5MPa and 7MPa respectively were put forward. When steel slag and blast furnace slag was composited in proportion as 1:2, properties of mortar abrasion resistance, resistant to alkaliaggregate reaction and resistant to penetration of chloride ion were improved greatly than reference mortar. The samples prepared for fatigue test obeyed two-parameter Weibull distribution, thus two fatigue equations at different stress levels and different failure probabilities were concluded.
