Abstract |
This study evaluates the shear performance of precast beams with ground granulated blast furnace slag. A total of four specimens according to replacement ratio of ground granulated blast furnace slag. The specimens under three loading points had a shear span-to-depth ratio of 2.5, and a rectangular section with a width of 200mm and a effect depth of 300 mm. In this study, existing equations were used for predicting the shear strength of the specimens. The shear strength by existing equations was compared with those of 89 reinforced concrete beams without shear reinforcement. It can be shown from experimental results that all specimens with ground granulated blast furnace slag showed a similar shear strength as compared with the specimen with portland cements alone.
