고로슬래그 미분말을 사용한 프리캐스트 RC 보의 전단성능에 관한 실험적 연구

This study evaluates the shear performance of precast reinforce concrete beams with ground granulated blast furnace slag (GGBS) cements. The specimens with various replacement ratios of GGBS (0%, 30% and 50%) were cast and tested in shear. As a result, it was found that the specimens with 30% and 50% GGBS showed a similar shear strength compared to the specimen with portland cements alone.
