To understand the structural behavior of RC beams made of concrete, where part of the cement is replaced with ground-granulated blast-furnace slag, shear-bending tests were conducted on RC beams using the replacement ratio of ground-granulated blast-furnace slag as the experimental variable. The results showed that even for a 70% replacement ratio of the ground-granulated blast-furnace slag, the beam exhibited hysteresis characteristics and damage properties equivalent to those of a normal RC beam without ground-granulated blast-furnace slag.
