The coal-fired power plant shows the increasing tendency from excellent in stability of the raw material supply and the economy, and, therefore, the amount of generation of the coal ash is expected to increase greatly, too. Considering such a current state, JIS A 6201 "Fly ash for use in concrete" was revised in 1999 aiming at the widely use as an admixture for the concrete. The quality of fly ash was classified into four kinds by this revision, and effective use to the field corresponding to each quality became possible. However, the actual results of coarse fly ash newly added (kind IV) are not accumulated enough in this existing state. In this study, to extend the amount of effective use of fly ash, many kinds of concrete using fly ash as a part of fine aggregate or as the admixture for self-compacting concrete were examined.
