Abstract
There have been many studies on strength development and durability of concrete containing ground granulated blast-furnace slag (BS). Recently, concrete with a high content of BS is studied as a means of carbon-dioxide reduction. However, few studies have been carried out on the shear capacity of reinforced concrete (RC) beams with a high BS content. The purpose of this study was to investigate the shear resisting mechanism of RC beams with a high BS content by shear loading tests. The important findings in this study were as follows: (1) both compressive strength and elastic modulus of concrete containing BS were smaller than those of normal concrete at the age of 28 days; (2) BS concrete exhibited increased shrinkage as compared with normal concrete until the age of 28 days; and (3) shear capacity of the RC beams containing BS was 11% lower than that of normal RC beams with equivalent compressive strength.
