Abstract
Recently there are an increasing number of studies about concrete with a high content of ground granulated blast-furnace slag (BS) as a part of efforts for reduction of carbon-dioxide emissions. However, little has been studied about the shear capacity of reinforced concrete (RC) beams with a high BS content. In this study, shear loading tests of RC beams with a high BS content were performed to investigate the shear load resisting mechanism. Some of the important findings were as follows: (1) normal strength concrete with blast-furnace slag cement (BSC) exhibited a larger shrinkage compared to concrete with ordinary Portland cement (OPC) or fly ash cement (FAC) of equivalent compressive strength until the age of 28 days; and (2) shear capacity of the normal strength RC beam with BSC was lower by about 10% compared to that of RC beams with OPC or FAC of equivalent compressive strength at the age of 28 days.
