- Synopsis
- The use of slag, a by-product from ironworks, as concrete aggregate has been restricted in the standard specifications for design of concrete structures, because unspecified minerals in the slag may cause some damage on reinforced concrete structures. Recent studies showed that the expansion of the slag can be effectively controlled if steam processed slag is used with fly ash, which enabled the application of the material to some shore concrete structures. However, the mechanism of the expansion has not been fully understood. This report describes the research results on the expansion and control mechanism of blast furnace and steelmaking slag in concrete without natural aggregate �iFS concrete�j. Also, the properties of the FS concrete such as strength, seawater resistance and the behavior of the reinforced concrete members using FS concrete are demonstrated in this paper.
