摘要：

Air quenched basic oxygen furnace steel slag(BOF-SS)is processed at very high cooling rate,which is expected to have different cementitious properties from conventional slowly cooled BOF-SS.For this purpose,the strength activity indexes of air quenched and slowly cooled BOF-SS are investigated.The results reveal that,under the specific surface area(S) of 490m2/kg,the compressive strength activity index reaches 1.24 after 28days with replacement of 15% air quenched BOF-SS and reaches 1.05 after 28days with replacement of 20% air quenched BOF-SS and 30% granulated blast furnace slag(GBFS).The cementitious activity of air quenched BOF-SS is obviously higher than that of slowly cooled BOF-SS,mainly because it contains more C3S and glassy phases.
