Abstract

This study was carried out to present the properties of fresh concrete made with ground granulated blast-furnace slag (BFS) powder with variations of blaine and content, and to estimate the utilization of the BFS concrete as admixtural materials for concrete structures of the building. According to the results, the fluidity of concrete which BFS dosage rate was 45% had the considerable difference from that of concrete which BFS dosage rate was not bigger than 35%. Also, the diminution of bleeding was appeared with the increase of blaine and content of BFS. It is concluded that BFS concrete of low blaine can be used effectively in concrete structures of the building.
